Arson ruled out in Frensham Common fire
Arson has been ruled out as the cause of one of three recent fires on Surrey heathland.
Police said the fire at Frensham Common, off Old Frensham Road, Farnham, which started on Tuesday, was not being treated as suspicious.
The RSPB said it feared for wildlife at the seven-hectare site, which was finally put out on Thursday.
Surrey Police said it was investigating three other fires believed to have been started deliberately.
Another fire, which also started on Tuesday, in Ash Hill Road, Ash, is being treated as suspicious along with one at Ashtead Common, off Kingston Road, Leatherhead which broke out shortly after midnight on Monday.
An investigation is continuing into a fire at Pirbright ranges which started on 15 April and reignited three days later.
A 33-year-old man from Ash Vale, arrested on suspicion of arson at Pirbright, has been released on bail until 30 May.
Surrey Fire and Rescue Service said two specialist vehicles would continue to patrol the scene and keep a watching brief to dampen down any hotspots.
"We are asking for the public to be vigilant and to call us straight away if they spot anyone acting suspiciously around heath and common land," said Det Ch Insp Martin Goodwin.
"These fires have caused a huge amount of disruption and inconvenience to the local community and have stretched the resources of the emergency services.
