Detectives from East Surrey CID are appealing for information following two burglaries in Copthorne.
At least three intruders, dressed in scarves and balaclavas, entered a property in the Domewood area at around noon on October 7.
Once inside the property the offenders shouted to the occupant but quickly left the scene. A second property had been also been entered nearby at around the same time.
Officers are trying to ascertain if anything was stolen during either break-in.
Detectives Constable Tracey Brocklesby said: “This was clearly a well-planned and organised offence which occurred during daylight hours, therefore, I believe someone, somewhere must have seen something which connects to the burglaries.
“I would appeal to anyone who saw anything suspicious in the days and weeks leading up to the offences, in particular I would like information on a dark coloured saloon car which was seen near both addresses around the time of the offences.”
Witnesses are asked to contact Surrey Police on 101.
