Police have issued a warning to homeowners following an attempted burglary on Devonshire Road in Blackpool.
A suspected burglar attempted to gain access to a bungalow on 22 February at around 12.15pm using a screwdriver to prise open patio doors, say police.
The burglar was then disturbed by family members who were in the house and the burglar made off empty-handed, they added.
Sergeant Danielle Freaney said: "In the last 31 days there have been 27 burglaries in our area and many of them have gained entry via patio doors.
"There appears to be a pattern where the offender knocks on the front door and on hearing no answer, goes to the back of the property to break-in.
"We would like to remind the public to remove keys from the locks of patio doors and to take extra care if they are planning to leave their property for a length of time.
"If you know you are going to be away it is possible to report that your property will be unoccupied to police on 101. They will then be able to place a marker so that police will be aware in case of any suspicious activity."
