Police are carrying out patrols of Wellingborough market after traders complained of yobs hanging around near stalls.
Some traders have complained to Wellingborough Council about issues caused by anti-social behaviour on market days.
Council staff have contacted police about increasing patrols in the area.
The issue was highlighted at a recent council meeting.
Jennifer Bell, project coordinator at Wellingborough Council, said: “We have asked if there could be an increased police presence on the market.
“A lot of the traders say that they don’t feel safe because of anti-social behaviour, and some even say that they pack up early on a Saturday.”
Inspector Pauline Sturman, Wellingborough sector commander, said: “In relation to reports of anti-social behaviour issues within the market area, PC Ian Butler is working with the representatives from the market traders group and local shops to address the issues raised.
“Focused patrols are ongoing and relevant action taken against those suspected of anti-social behaviour activity.
“This supports targeted enforcement work that has been ongoing in that area over the last six months.”
