POLICE were today investigating a possible arson attack on a Worcester mental health centre which is undergoing a £1.2m refurbishment.

Three crews were scrambled to the Studdert Kennedy Day Centre, in City Walls Road, after smoke was seen billowing from the building at 8.30pm yesterday.

Firefighters spent four hours ventilating the building, which was heavily smoke-logged.

Police also attended as a neighbouring building had been hit by an arsonist days earlier.

A West Mercia police spokeswoman said forensic experts were on site searching for clues that pointed to arson.

The day care centre is empty while builders carry out the Government-funded refurbishment.
