Gangs and gang crime

Gangs are street-based groups who see themselves (and are seen by others) as a discernible group for whom crime and violence is an integral part of the group’s identity.

In terms of safeguarding children and young people, gang involvement is increasingly recognised as a form of Child Criminal Exploitation. Any organisation that works with young people should be aware of the risks and alert to the signs of gang involvement. 

In most contexts, belonging to a gang isn’t against the law, it is the criminal offences committed by gang members that are illegal. In Northern Ireland, gang involvement is often associated with paramilitary groups. Many paramilitary groups are banned under the Terrorism Act 2000. It is against the law to belong to, support or promote these groups. 

Gang membership can be linked to illegal activity, particularly organised criminal gangs involved in trafficking, drug dealing and violent crime.
