A dispersal order to combat anti-social behaviour over the Halloween and Bonfire Night period has come into effect on part of Teesside.
Police patrols are being stepped up in the Greater Eston area until the order ends at midnight on 8 November.
It gives officers the power to break up groups of two or more people they believe could cause trouble.
Police said there was a significant rise in anti-social behaviour during the same period last year.
The period also includes the school half-term holiday week.
Insp Guy Hall, of Cleveland Police, said: "We will be carrying out high visibility patrols in the area with officers on foot and on bikes using head cams.
"The mounted section and CCTV van will also be assisting with the patrols."
