An empty warehouse in Leicester has been set on fire for the fourth time in 15 months. Three fire engines were called to the fire at the old Bestway cash and carry building on Loughborough Road.
People living in the area complained of thick black smoke covering homes and cars - mostly caused by old tyres which were quickly put out.
Two youths were detained by police at the scene and taken to nearby Melton Road police station.
Another two youths were questioned by police about the incident.
A fire service spokesman warned if the semi-derelict building is not demolished soon someone could lose their life.
