Police presence in Bristol is being stepped up on Halloween to reassure the public and deal with disorder and anti-social behaviour.
Operation Bewitched will see extra officers on duty and Community Support Officers out in neighbourhoods.
Insp Andy Bennett said: "We will not tolerate anti-social behaviour under the guise of trick or treat."
Police are also setting up agreements with local shops not to sell eggs and flour to young people.
Insp Bennett said: "There will be a high visibility presence right across Bristol over Halloween to reassure the public and also to make sure that trick or treating and all the other Halloween fun stays fun and doesn't turn into anything else."
