A man has been left seriously injured after an attempted robbery in East Renfrewshire.

The 32-year-old victim was inside his white Audi car on Hill Avenue, Newton Mearns, when a man opened his passenger door and seriously assaulted him around 2.20am on Saturday.

The attack caused the driver to hit the accelerator pedal and collide into a parked car in front.

The victim ran for help, but was chased by his attacker and three other men before being assaulted again.

The male suspects, believed to be aged between 16 and 18, fled when a passing motorist stopped to assist the injured man.

The victim is now receiving treatment at Queen Elizabeth University Hospital in Glasgow.

Officers are carrying out door-to-door enquiries and gathering CCTV images from around the area.

Detective constable Joseph Keith said: "The motive for this attack is unknown and a man has sustained serious injuries.

"I appreciate the incident occurred in the early hours of the morning but it's possible someone saw or heard something.

"Perhaps someone saw the four men hanging around Hill Avenue and thought nothing of it at the time, however, in light of this crime, any information could prove vital and I would urge people to get in touch with us."
