An appeal has been launched after three properties on a road in Hartlepool were burgled on the same night.
Police say the burglaries took place on Victoria Road overnight between Thursday, May 24 and Friday, May 25.
Cleveland Policy say a large amount of damage was caused to the buildings after a large number of tiles were stolen from roofs.
A spokesman for the force said: "A large quantity of lead tiles and roof tiles were stolen from the premises.
"As a result of the burglaries, a large amount of damage has been caused to the buildings which will be costly for the owners to repair."
