Councillors and police are monitoring complaints about the new skatepark being built on the Rec in Stamford.
Town councillor Max Sawyer told a full council meeting on Tuesday that six complaints had come from the same resident over the work.
All the complaints had been investigated and found to be unsubstantiated.
Coun Sawyer said: “There is some indication of friction between this person and young people in the area.”
Coun Sawyer said police had been told of the complaints and were keeping an eye on the situation.
