<h2>Swoop on spud gun boy</h2>
ARMED police swooped on a residential street to arrest a boy with a spud gun.
Police were called to Winston Crescent, Biggleswade, to a report of a youngster carrying a firearm.
The force helicopter was scrambled, an armed unit was sent out, and the road closed off.
But when officers visited the 15-year-old's house, it turned out the only weapons in his possession were a potato gun and a BB gun.
He was cautioned following the incident on Wednesday night.
A spokesman for Bedfordshire police said: "The firearm turned out to be a spud gun, but the person who called the police did exactly the right thing. If you have any sort of gun at all, don't carry it in public."
