Chemical alert may be false alarm

A chemical alert, which closed a street in Warwickshire, may have been a false alarm.

Regent Grove in Leamington Spa was closed on Sunday after a white substance was pushed through the letterbox of a Muslim community centre.

Warwickshire Police believe the substance may be from a fire extinguisher but are waiting for confirmation.

Fifteen people who were kept in quarantine behind police lines have been released.

More than 20 firefighters were called out to street just before 1300 BST following the discovery.

Fire crews wearing full chemical protection suits attended the scene.

Ambulance, police and an environmental protection unit has also been called to the scene.
