RAIDERS scoured a house before leaving empty handed on Friday.
Thieves broke into the Mersea Road home in Colchester by forcing the front door lock between 11.30am and 12.10pm.
They searched inside but nothing is thought to have been taken.
Police are calling for information after a man was seen acting suspiciously in the area at around the time of the burglary.
He is described as being dressed in dark clothing with a hood or a hat.
Anyone with details should call PC Caroline Cross at Colchester CID on 101 or Crimestoppers anonymously on 0800 555 111.
