THIEVES broke into a shed at the back of a Berwick restaurant last Thursday and stole a bike.
A one-hour window was all the burglars needed to steal the black and yellow bike, valued at $1250, from the Clyde Road property.
Police said the thieves broke the lock on the shed between 4.30pm and 5.30pm.
A helmet was also stolen.
Anyone with information about the bike is asked to contact Narre Warren Police on 9705 3111.
