Officers from Swindon CID are appealing for any information regarding a fire at a convenience store in Pinehurst.
They were called to the One Stop shop in The Circle by Dorset & Wiltshire Fire & Rescue Service shortly before 8pm on Thursday 12 July.
The fire is believed to have started outside the rear of the store and quickly spread inside.
DC Stephanie England said: “We are currently treating this fire as arson and as part of our ongoing investigation, we are really keen to speak to anyone who was in the area of The Circle last night between 7.15pm and 7.45pm and saw any suspicious activity near to the store, especially to the rear.
“We are aware that there were people nearby when the fire started and we understand some of these people may have filmed or taken photos of the incident. If you have footage which could help our investigation, please get in touch.
“This fire has caused significant damage to the shop and will no doubt be a huge inconvenience to all those living in the area, as well as staff at the shop and residents who live in the flats which have been impacted by the fire.”
