An area of Spalding, including Ayscoughfee Gardens and The Vista, plagued by vandalism and disorder has been targeted again.
A first floor window at Ayscoughfee Hall and a side window at St Nicolas Hall, The Vista, were smashed between 5.30pm on Sunday and 10.30am on Monday.
Police suspect that a football may have caused the damage to the window at Ayscoughfee Hall, but is not yet known whether the two incidents are linked.
They are the latest in a series of attacks in the area over recent weeks and police are steeping up patrols amid reports of youths hanging around near the derelict Bull and Monkie pub.
Anyone with information should call 101.
