Two shops in Worthing were broken into overnight on Thursday (February 9) and police are appealing to anyone who may have witnessed anything suspicious.
It is believed that the burglars broke into one of the stores in South Street in order to gain access to another, which was next door, to steal the safe.
The break-ins are thought to have happened at about 10.40pm and detectives would particularly like to hear from anyone who saw up to three people wheeling a white washing macine-sized object along Warwick Street.
A police spokesman said: “We are hoping that by releasing this information it might jog someone’s memory. If you were in the area at the time and saw something unusual then we would ask you to pick up the phone and contact police as soon as possible, quoting serial 0209 of February 10.”
