Around 30 firefighters were called to the scene of a large fire near an industrial estate in Hampshire.
Crews were called at 3.41pm on Saturday (13 August) to tackle the blaze involving five hectares of grass and woodland near Calmore Industrial Estate.
Police officers are now investigating the incident after five fires were set in the Testwood Lake and Test Lane area of Totton.
The Hampshire Fire and Rescue Service Control Room received more than 25 emergency calls reporting the fire.
Hose reels and jets were operation, with firefighters working to create a fire break in order to protect nearby property.
People are urged to avoid the area as crews work to stop the fire.
