Residents are being warned not to leave goodies for window-shopping thieves - If you love it, lock it.
Police chiefs issued the warning following a spate of burglaries and vehicle crime over the weekend where doors and windows have been left open and cars and vans found insecure.
Said Superintendent Eddie Murphy: “We believe many of these crimes are linked. It’s clear that opportunist criminals are just going around areas, trying doors or handles and looking for anything valuable.
“Don’t give them an invitation to enter your home or vehicle by leaving doors unlocked or items on view.
“It’s so frustrating because most, if not all, of these incidents could have been avoided.
“If people just take simple crime prevention steps it will mean less work for police, but more importantly, it’ll mean that people foil thieves and keep their possessions.”
A burglar entered a home at Burghwallis Lane, Burghwallis, through an unlocked kitchen door between 7.50pm and 8.30pm on Sunday, 8 December, while the resident was walking a dog.
They took the car keys from the side, then drove off in the owner’s Ford Mondeo.
Meanwhile there were three burglaries in Balby at the weekend, which police believe are linked.
At Alexandra Road between 8pm on Saturday and 2am on Sunday, a resident had left a bedroom window open. A burglar climbed onto an outbuilding and then inside to steal a television and computer worth £600.
Between 11.30pm on Saturday and 6am on Sunday, a burglar struck at a house on St John’s Road, entering through an insecure front door while the occupant had gone to bed. The culprit escaped with a purse and phone worth £250.
And between 2.45am and 6.45am on Sunday, a burglar walked through an unlocked front door at a Lambeth Road house and made off with a TV, computer and iPad, together valued at £1,200.
Officers believe five cases of vehicles, which were found insecure after being searched by thieves, are linked.
Three, between Saturday afternoon and Sunday morning, were on the same road – Edencroft Drive at Edenthorpe. A sat nav was stolen from a Honda Civic between 9.30pm on Saturday and 5am on Sunday. Thieves also searched a Ford Fiesta and a Renault Master van, but nothing was stolen.
Culprits also searched a Nissan Juke, parked on Newhall Road, Kirk Sandall, overnight from Saturday into Sunday.
But the owner of a Ford Fiesta at Aidan’s Close, Clay Lane, was not so lucky as a thief escaped with a sat nav from the vehicle between 1am and 9am on Sunday.
Two Bessacarr incidents are also thought to be linked with each other. A sat nav was taken from a Vauxhall Insignia at Lindrick Close between 4pm on Saturday and 10am on Sunday, while a VW Passat on the same road was searched but nothing was stolen.
A man delivering packages at 3.50pm on Saturday at Lothian Road, Intake, had a parcel taken from the unlocked boot of their Ford Mondeo.
And a BMW 3 series car, parked at Newhall Road, Kirk Sandall, had £60 cash and an iPod stolen between 1am and 10.05am on Sunday.
