A mother has made an impassioned appeal for the return of her son's stolen bike.

Marie Marshall has pleaded for anyone with information on the whereabouts of her son Toby's bike to come forward after it was stolen on Tuesday afternoon.

Toby, who turned 15 last week, was visiting a friend on Lindisfarne Street off London Road in Carlisle when the grey Marin mountain bike was taken.

"It's worth a lot of money," said Carlisle mum Marie, adding that the theft took place at about 5.15pm on Tuesday.

"He got it for Christmas just over a year ago, but Toby paid for half of the bike himself because we couldn't afford to pay for all of it."

"He uses it for his paper round. He goes everywhere on it, it's his life really."

The full suspension mountain bike has bright blue lettering down the side, with pink handle grips.

Cumbria Police, who are currently investigating the incident, confirmed that they have arrested two 14-year-old boys on suspicion of theft.
