More than 60 shoppers met police when they held a surgery at a supermarket.
Members of the public could raise concerns with two PCSOs in Tesco, Turnells Mill Lane, Wellingborough, on Saturday.
PCSO Phil Wane said: “It was good. People were very, very happy to see us.”
The officers directed them to other agencies if needed.
Gary Horsford, 37, of Wellingborough, said: “Some people don’t like going to the police station.”
