Three arrests over hospital site fire in Northampton
Three people have been arrested on suspicion of arson in connection with a fire that ripped through a derelict hospital in Northampton.
At its height more than 80 firefighters tackled the blaze at the former St Crispin Psychiatric Hospital on Berrywood Road on 6 August.
Police said three men, two aged 23, and one aged 20, have been arrested and released on police bail.
A woman, aged 20, has also been interviewed voluntarily.
A Northamptonshire Police spokesman said: "Police are continuing to investigate the circumstances of how the former St Crispin's Hospital was set alight on 6 August .
"A number of people have been arrested and interviewed by detectives in connection with the fire."
Fire investigators said the 19th-century building involved in the fire had been left "structurally unsafe" after it was extensively damaged by the blaze.
The hospital opened in 1876 and was closed in 1995.
