PENZANCE'S police chief is warning householders to take extra care of their household security arrangements.
The appeal by Inspector Jean Phillips follows several recent burglaries in the town when intruders have taken advantage of open doors or windows to gain entry to a property.
Inspector Phillips said: "I would ask all residents to review their security to ensure their windows and doors are closed and locked at night.
"I would also urge people to make sure they are locked during the day when they are in a different part of the house."
The three burglaries are:
Overnight January 3/4 in High Street, Penzance. The intruder broke into a house at the rear of the premises and took an Acer laptop, a quantity of cash, birthday cards and a Panasonic camera; crime ref, AP/14/17.
December 20 at Penrose Terrace, Penzance. The offender made his way into an insecure porch and stole parcels; crime ref, AP/14/17.
In the early hours of January 2 at Lyn Terrace, Newlyn, entry was made into a property through the rear yard and an insecure window at around 2am.
The occupants disturbed the intruder who made off with bank cards and keys; crime ref: AP/14/12.
If anyone has any information about any of these incidents, call the police on 101 or Crimestoppers on 0800 555111.
