THIEVES tried to gain access to a factory in Droitwich, damaging the lock to the front door and accessing an office.
The premises, in Pointon Way, Hampton Lovett, was targeted between 6.20pm on Thursday and 6.30pm on Friday.
After getting into the office they used a tool in a bid to break a lock but were unable to.
The raiders then noticed a CCTV camera and tried to conceal their identity before leaving the scene via the main entrance.
