A 21-year-old man is in a critical condition in hospital after a crash on the A82 near Loch Lomond.

The man was a passenger on a motorbike which was involved in a collision with an estate car between Balloch and Arden at around 5.10pm on Monday, August 31.

Police say the black Suzuki motorbike, with two people on board, was travelling northbound near the junction with Auchenheglish Lodges when it slowed to turn right.

It was then involved in a crash with a silver Volkswagen Golf estate, which was driving behind them.

The driver and the passenger were thrown from the motorcycle onto the northbound carriageway.

The 21-year-old passenger was then taken to the Queen Elizabeth University Hospital where he is now in a critical condition.

The 23-year old-driver of the bike was taken to the Royal Alexandra Hospital in Paisley and was later discharged.

The 46-year-old driver of the Volkswagen Golf Estate was not injured.
