BIKES were stolen from two backyards in Ashington in one day last week.
The bikes were stolen from homes in Fontburn Crescent and Woodhorn Villas a week ago on Tuesday.
The bikes had been left unattended and unsecured.
Chief Inspector Peter Reeve, of the police’s Northumberland area command, said: “With the warmer weather upon us and lighter nights, more people are using their bikes.
“I understand people may feel tempted to leave a bike lying in the garden or against a wall, but this is leaving it wide open to opportunist thieves who will take seconds to make off with it.
“I would urge people to get into the habit of locking their bike to something secure when they leave it unattended, even if it’s only for a short time.
“Anything which makes it harder for thieves will reduce the risk of the bike being stolen in the first place.
“People spend a lot of money on bikes, so it’s worth spending that little bit more on buying a good-quality lock and ensuring it’s used.”
“I’d also ask people to take a note of their bike’s frame number and other details such as make and model to make it easier for it to be reunited with the owner if it is lost or stolen.”
Police are appealing for anyone with any information to contact them on 101 ext 69191.
