Storage containers in Horsham have become the target of break-ins.
Several padlocks have been broken off from the units in Blatchford Road some time early this week.
Nothing has been reported as stolen, but officers have not ruled out the possibility.
Sussex Police has launched a witness appeal.
PCSO Emma Walsh, of Horsham police, said: “It would appear that nothing has been taken from one of the containers.
“However, each container is individually owned so it is unknown yet whether anything has been taken from the others.”
Anyone with information can contact Sussex Police on 101 quoting serial number 0169 of 22/11/2013.
Alternatively members of the public can contact charity Crimestoppers anonymously on 0800 55 111.
