A woman was threatened with a knife in Chorley after she intervened in an argument in supermarket car park, say police.
Officers were called around 10.50pm on October 5 following the incident at Asda in Bolton Street.
A 25-year-old woman said that she was in the car park when she witnessed an argument between two men around 10pm.
The victim approached one of the men and told him to stop and get into his car.
The man then started to verbally abuse the woman before pulling a knife from his car and walking towards her.
She told the suspect to get back in his car again with the man returning to the vehicle, a blue Volkswagen Golf, before making off from the scene with a female driver.
