Hard-pressed Lancashire fire crews were this afternoon dealing with a new wildfire caused by arsonists
Officers were alerted after smoke was seen coming from woods at Healey Nab, near Chorley, this afternoon.
Three fire crews and a helicopter carrying water went to the scene.
Scores of officers were already deployed at Winter Hill - about four miles away - and also helping out Greater Manchester colleagues at Saddleworth.
A Lancashire Fire and Rescue spokesman said the blaze was being treated as suspected arson.
He said there were two seats of fire.
Police had been informed and the Barton-based police helicopter had been mobilised.
