From the Lancashire constabulary website:

POLICE in West Lancashire are urging residents to remain vigilant to the threat of burglary.

The warning follows an increase in offences over this month as a direct consequence of homeowners leaving front doors insecure or garden tools in their gardens which are then used to force windows and doors.

There have been nine burglaries so far this year in the Ormskirk policing area where police have seen spades and hoes used to force entry, or where a window or door has been left unlocked.

There is more information on their site including advice for householders to reduce the risk of burglary.
