Pursue
The aim of Pursue is to stop terrorist attacks happening in the UK or against UK interests overseas. The main objectives of Pursue are to detect, understand, investigate, and disrupt terrorist activity. There are multiple types of terrorists that are being pursued under this system, including:
International terrorist groups, such as Al-Qaeda.
Domestic terrorist groups, such as Islamist movements in London responsible for the 7 July 2005 London bombings, and further attacks in 2017 such as the Manchester Arena bombing.
Lone wolf attacks, for example Darren Osbourne, the perpetrator of the 2017 Finsbury Park van attack.
Hostile nation states, for example Russia's involvement in the Poisoning of Sergei and Yulia Skripal, also known as the Salisbury Poisonings.
Counter Terrorism Policing work with MI5 to develop intelligence, and with the Crown Prosecution Service to put compelling evidence before the courts. The public can also support law enforcement to pursue potential terrorist activity through calling the anti-terrorist hotline. Action Counters Terrorism (ACT) encourages individuals to report suspicious activity which could be related to terrorism through online reporting, or by contacting the police in confidence on their dedicated phone number.
Government departments and agencies work collaboratively to disrupt terrorist activity. Counter-terrorism policing, MI5, and wider intelligence work together closely to investigate, detect, and disrupt terrorism, alongside the Criminal Justice System. The Ministry of Defence is a key contributor to CONTEST strategy. It particularly supports Pursue through its military capability to disrupt overseas terrorist groups and its support of overseas law enforcement and security agencies. Its support for conflict prevention work has also contributed to the CONTEST objectives. Work overseas is crucial to Pursue, as previous UK attack plots have had support from terrorists overseas, as well as UK individuals being radicalised while overseas. Working with international partners therefore attempts to disrupt the threat before it manifests itself in the UK.
An important element of Pursue is the independent oversight regime, which scrutinises the significant powers and tools used to stop potential terrorist attacks, ensuring they are used proportionately and appropriately.
Proportionality (law) must be considered when using broader powers for terrorism investigations. The Secretary of State must be satisfied that the information obtained could not reasonably have been obtained by any other means. The intelligence gain must be sufficiently great to justify an intrusion, as well as any unavoidable collateral intrusion against individuals other than the target. The Regulation of Investigatory Powers Act 2000 ensures that investigatory techniques are used in a way that is compatible with the Article 8 right to respect for private and family life, as in the European Convention on Human Rights.
Pursue is becoming increasingly complex as the threat of terrorism continues to diversify. Between 1 January and 31 December 2022, 169 persons were arrested for terrorism related activity, with 232 persons held in custody for terrorism-connected offences. From 2017 to July 2023, MI5 and the police have disrupted 39 late stage attack plots.
Within Pursue there are different elements of strategy involved: detection, prosecution, punishment, control, and disruption.
Detection involves gaining specific reliable information and evidence. This may require the use of various surveillance methods such as hacking for digital information, or human surveillance through undercover policing. There are specific powers which can be utilised for these purposes, such as the specific power of arrest on suspicion of a terrorist, under section 41 of the Terrorism Act 2000. Additionally those within the Investigatory Powers Act 2016, such as targeted interception, which involves requesting a warrant from the Secretary of State to intercept transmission of communications.
There is information related to security and intelligence, and special investigation powers which is protected by the Official Secrets Act 1989. This provides legal protection against unauthorised disclosure of information and espionage, and protest certain tactics of information gathering.
Under section 41 of the Terrorism Act 2000 a suspect can be detained for a maximum of 14 day before being charged, compared to the maximum of four days under standard arrest powers. This allows more time for police to investigate and gather evidence in relation to the potential terrorism offences. Additional powers allow a senior police officer to delay a suspect's access to a solicitor and/or contact with a named person. This is authorised if they believe that exercising this right may result in any of the consequences listed in section 41 of the Terrorism Act 2000, for example sending out a dangerous message which may instigate an act of terrorism.
There are a number of extremist groups which are banned under UK law, as part of the counter-terrorist legislation. Section 3 of the Terrorism Act 2000 allows the Home Secretary to proscribe an organisation if they are concerned in terrorism. This means the organisation commits or participates in acts of terrorism, prepares for terrorism, promotes, or encourages terrorism.
Proscription must be proportionate, which means the following factors must be taken into account when deciding whether to proscribe an organisation:
The nature and scale of the organisation's activities
The specific threat posed to the UK
The specific threat posed to British nationals overseas
The extent of the organisation's presence in the UK
The need to support other members of the international community in the global fight against terrorism.
Between 2018 and 2023 there have been six terrorist groups proscribed, including extreme right-wing groups such as Atomwaffen Division and The Base (hate group).
The Terrorism Act 2006 introduced further established terrorist offences including the encouragement of terrorism, preparation of terrorist acts and terrorist training, and offences involving radioactive devices and materials and nuclear facilities and sites. An example of this is 19-year-old Matthew King who pleaded guilty to the preparation of terrorist acts, and has now been sentenced to life imprisonment.
In 2021 Shabazz Suleman was arrested and charged with terror offences under the Terrorism Act 2000. He has since pleaded guilty to preparing acts of terrorism by travelling to Turkey to join IS in Syria, as well as being charged with being a member of the proscribed group, IS, and receiving training in the use of firearms.
Although there are specific terrorist offences which are criminalised in the UK, the prosecution process remains the same, and prosecutors are tried fairly through the mainstream criminal justice system. The Crown Prosecution Service has a Special Crime and Counter Terrorism Division (SCCTD) to deal with the prosecution of terrorism cases. In 2021 Greer emphasised why this process is significant stating that it "... offers the best prospects of securing the legitimacy of counterterrorist law enforcement and of maintaining public confidence in it."
The Counter-Terrorism and Security Act 2015 contains more powers to aid the UK's response to the threat of terrorism; in relation to Pursue it enhances the ability of operational agencies to monitor and control actions of those posing a threat.
The Counter-Extremism Strategy was published by the UK Government in 2015 and focuses on disrupting extremism, as well as extremists' rehabilitation and reintegration into society. This is an example of the punishment and control elements of Pursue.
