Wiltshire Police are investigating a vehicle fire which happened in the car park of Cavendish Square yesterday morning.
The car was well alight by 2am, 10 December.
This comes just hour after fire crews from Swindon Fire Station extinguished a bin fire using buckets of water in Shrewsbury Road, Walcot.
A spokesperson for Wiltshire Police said: “Anyone who saw anything suspicious is asked to contact police, and officers are particularly interested in speaking to the driver of a white panel van who was seen in the area at the time and may be a witness.
“They should call PC Dan Travis at Gablecross Police Station on 101.”
