A motorist had his white Jaguar car stolen at knifepoint by a man who flagged him down to ask for help.
The 52-year-old was driving along Flemington Road in Cambuslang, South Lanarkshire, when he was hailed by a man standing beside a silver Ford Focus.
The man claimed to have a puncture and asked for a lift, but then pulled out a knife.
He ordered the man to leave the car and took him to a nearby field where he told him to lie down, before driving off in the Jaguar.
The victim saw a second man driving off in the Ford Focus.
After the suspects had driven away the victim made his way back onto the main road where he came across some cyclists who helped him contact police.
Officers are appealing for information about the incident which happened at around 3pm on Saturday.
The Jaguar was discovered burnt out in Netherhouse Road, Bargeddie, at around 3.30pm that day.
