A spokesman for Northamptonshire Police said: "We are currently executing a planned operation in Regent Square, Northampton, and have had to shut Grafton Street at the Regent Square junction.

"Officers are expected to be there for the next half hour with the road closures to be lifted shortly afterwards. There is no risk of harm to members of the public."

One nearby worker claimed to have seen two men being taken out the back of the flats, on the corner of Grafton Street, in cuffs by the armed officers.

"There was between eight and ten coppers with guns. They weren't just carrying little pistols I can tell you that.
