Police are investigating seven car fires in an area of Northampton, including three arsons in three hours.
All of the blazes were deliberately started in the Far Cotton area, with the latest ones happening in Ransome Road, St Leonard’s Road and Abbey Road in the early hours of Monday.
A spokeswoman for Northamptonshire Police said detectives believe the same culprit was responsible for each.
A resident of Abbey Road, whose Mini Cooper was torched and has subsequently had to be scrapped, said: “If it was not for the very quick response of the fire service, the damage to property may have been far greater and life itself could have been affected due to the close proximity to houses.
“The attacks are becoming more brazen and the threat to life is becoming greater as a result of these actions.”
Monday’s arsons were a Fiat Punto at 12.55am in Ransome Road, a Renault Scenic at 2am in St Leonard’s Court and the Mini in Abbey Road at 3am.
In the previous spate, the cars were parked in Penrhyn Road, Euston Road and Delapre Crescent Road, and were set alight between midnight and 2.30am, on Monday, July 20.
Officers said the front grills of each of the cars were deliberately set alight, causing extensive damage to the vehicles.
Witnesses or anyone with information about any of the attacks are asked to contact police on 101 or Crimestoppers anonymously on 0800 555 111.
