A former police station and magistrates’ court building is thought to have been targeted by arsonists for the second time in a week, according to emergency services.
Devon and Somerset Fire and Rescue Service said it was called to the blaze at the disused building on Heavitree Road, in Exeter, at 21:42 GMT on Thursday where two fires were found in different parts of the property.
A fire at the same building took place on Monday night.
The service said both fires were believed to have been started deliberately. Devon and Cornwall Police has asked witnesses to get in touch.
