A late night blaze at a village petrol station that could have caused a serious incident was started deliberately.
Detectives have now launched an appeal for information into the blaze in Hoghton earlier this month.
Police were called to the Old Oak Service Station, Hoghton Road, at 10.25pm on Sunday, January 19, following a report of a fire.
It is believed somebody climbed onto the roof of the kiosk and smashed through the tiles before pouring accelerant into the building and setting it alight. The petrol station was not open at the time and nobody was injured.
Firefighters from Bamber Bridge managed to get the incident under control before it threatened fuel pumps on the forecourt.
A Lancashire Fire and Rescue Service spokesman said: “If the fire had spread through the forecourt shop then, with the pumps being only 15 metres away, it could potentially have been serious.”
A joint investigation was carried out between police and the fire service after an initial inspection suggested the cause may have been suspicious.
DC Dom Webster said: “We are following up a number of lines of enquiry, but I am keen to hear from anybody who has any information about this incident. I am appealing to anyone who saw or heard anything suspicious in the area on the night in question to come forward.
“The Old Oak Inn is next to the garage and was open at the time the fire was started. If you were in the pub that evening and think you may have information which could help then please contact police.”
Anybody with any information can contact police on 101 or Crimestoppers anonymously on 0800 555 111 or on-line at Crimestoppers-uk.org.
