A collapsed man was reportedly dragged from a Mercedes and left in the forecourt of an Enfield petrol station in the early hours of the morning.
Police were called to a BP petrol station in Bullsmoor Lane at around 9am yesterday morning (June 10) after the man was discovered.
The man aged in his 50s was taken to hospital by the London Ambulance Service where he remains in a critical condition.
A 42-year-old man has been arrested in connection with the incident. He has been bailed pending further enquiries.
A police investigation has found that a silver Mercedes drove into the petrol station shortly before 5am.
The driver reportedly pulled the man from the car and left him on the ground before driving off.
The collapsed man, who police said had no visible injuries, remained there until emergency services were called later that morning.
Officers are now appealing for anyone who was driving in the area at the time of the incident to get in touch.
Anyone with footage, or witnesses who saw anything suspicious, are asked to call 101, quoting reference 2156/10jun.
To remain anonymous, members of the public are urged to contact Crimestoppers.
