The home of a widower with small children was targeted by a thief during a spate of burglaries in Garstang in which cash was stolen.
Police are urging householders to be on their guard and make sure doors and windows are locked following the thefts, which occurred around the town last week.
PC Dave Shaw said the neighbourhood policing team had increased patrols around the estates surrounding the town centre after five burglaries were reported over October 20 to October 23.
Bungalows in Derby Road, Dorchester Road, Cambridge Drive and Rutland Close were all targeted and in one incident £500 in cash and jewellery worth £400 was stolen.
PC Shaw said: “This spate of thefts has been a very worrying for residents and we are urging people to review their security and make sure all homes are locked and secure.
“At this time of year with the darker nights setting in, it is important to think about security and if you notice any suspicious behaviour to report it to the neighbourhood policing team.
“We have launched extra patrols in the area following these recent incidents and are continuing with our investigations.”
PC Shaw said it was understood the brazen thief had walked into the homeowner’s gardens and used bodily force to break into the properties before searching the homes for cash.
He added they were keen to hear from any members of the public who may have witnessed anyone walking around the estate the evening of Saturday, October 20 from 6pm onwards or anyone who may have seen any suspicious vehicles.
In one incident a bungalow on Dorchester Road was targeted, while the homeowner attended a church service.
The thief broke through a back window before searching the property.
It happened between 6.15pm and 7.50pm on Saturday October 20.
Police believe the burglaries on the neighbouring roads are linked and all occurred around a similar time. Anyone with information should contact Garstang Police on 01995 607869 or call 101 or Crimestoppers anonymously on 0800 555 111.
