Police officers in Bolton have been authorised to carry out increased stop searches, in response to intelligence received from the communities and social media.
Under Section 60, officers can stop search anyone in a defined area at a specific time.
Those carrying dangerous instruments or offensive weapons will be prosecuted.
Chief Inspector Martin Ashurst, of GMP’s Bolton district, said: “We’ve made the decision to authorise Section 60 powers to prevent violence and keep people safe.
“Alongside increased stop searches, we have deployed extra uniformed and non-uniformed officers.
“I would like to use this opportunity to appeal to parents/ carers to talk to young people about their plans for the weekend to ensure they are both safe and legal.
“GMP will not tolerate violent crime – preventing and reducing it is one of our highest priorities.”
