Residents in the St Pauls, and Easton areas of Bristol should not be alarmed at extra police activity in the area, Avon and Somerset Constabulary said.
A force spokeswoman said the move was in response to outbreaks of violence between young people, and officers were there to deter further incidents.
She say residents could see officers making more use of stop-and-search powers during the operation.
Residents can find out more by calling at Trinity Road police station.
Ch Insp Catherine Johnstone said: "Our officers are there mainly to gather intelligence about recent events, and to provide a highly-visible presence to ensure that people feel safe in their communities.
"We know that using stop-and-search powers often causes tensions between the police and local residents.
"We wanted to inform people to the fact that this is being done in the interests of public safety. As always protecting the public has to be our number one priority."
