Police are hunting arsonists who targeted cars in the Strathfoyle area of Londonderry.
The vehicles were set on fire in Garrymore Place in the early hours of yesterday morning.
Sergeant Adrian Brogan said: "Officers arrived at the scene at 1.30am and at that stage, one car - a white BMW 3 series - was engulfed in flames and a second - a blue Renault Clio - was also on fire. The garage doors at the house were also well alight and there was scorch-damage to a neighbouring garage."
The Fire and Rescue Service are treating it as arson. No-one was injured in the incident.
"As part of our investigation, we would like to talk to two males who were seen in the area, close to the address, in a dark-coloured car. It was reported that they threw liquid over one of the cars and set it alight before driving away at speed.
"The car was then seen travelling from Garrymore Place, down Clonmeen Drive and onto the Temple Road," added Mr Brogan.
