The police are appealing for information after a three vehicle road traffic collision in north west Sutherland.
Emergency services were alerted to the incident on the A837 approximately four miles north of the Ledmore junction at 4.40pm yesterday afternoon.
The collision involved a red Porsche 911 car and two Kawasaki motorcycles.
The two female motorcyclists – aged 23 and 22 – were airlifted to Western Isles Hospital in Stornoway immediately following the incident.
The 23-year-old has since been transferred to the Queen Elizabeth Hospital in Glasgow for treatment to serious but not life-threatening injuries.
A 47-year-old man will be the subject of a report to the Procurator Fiscal in connection with the incident.
Sgt Donnie Mackinnon, of the road policing unit, said: "Our enquiries are ongoing and we are appealing for witnesses to the collision to contact us as soon as possible.
"Anyone with information or anyone who saw these vehicles on the road should call us on 101, quoting reference NE12553/17."
