Dispersal zones will be in effect across Liverpool city centre for a second consecutive weekend.
Police are continuing to crack down on anti-social behaviour by enforcing the two separate areas between 6pm today and 6pm on Sunday, medicine November 13.
The first includes the Bronte estate, the area bound by London Road, Pembroke Place, Seymour Street, Russell Street, Brownlow Hill and Great Newton Street.
A second dispersal zone will be in effect in the area covering Smithfield Street, Cockspur Street, Vauxhall Road, Midghall Street, Marybone and Tithebarn Street.
Police have exercised the ruling under Section 34 of the 2014 Anti-Social Behaviour, Crime and Policing Act.
It means officers and community support traffic officers can direct people they suspect are causing or likely to cause crime, nuisance or anti-social behaviour to leave the area for up to 48 hours.
If a person has been directed to leave the area and returns during the period of the dispersal notice, an offence will have been committed and can lead to their arrest.
Inspector Steve Hardy said: “We have had reports of persistent incidents of anti-social behaviour including criminal damage to properties and vehicles and fireworks being thrown on the Bronte estate.
“In the Marybone area we have had reports of threatening and intimidating behaviour by groups of youths.
“The zones are not about bothering people, young or old, who are going about their legitimate daily business.
“However, we will be targeting people who are intent on causing anti-social behaviour or criminal damage, especially if they are gathering in large groups, which can be intimidating to others.
“The zone gives officers the powers they need to deal effectively with people behaving anti-socially and I would urge anyone who is suffering from anti-social behaviour to contact us so that we can take action.”
People can call officers on the 101 number, 999 in an emergency or Crimestoppers on 0800 555 111.
