POLICE officers have launched an investigation into a huge crash which left two people hospitalised with serious injuries.

Essex Police was called to reports of a collision involving three vehicles on the London-bound A12 between Colchester United and the Avenue of Remembrance at about 9.30am on Monday.

A woman and a child were airlifted to Addenbrooke’s Hospital, Cambridge, with serious injuries after being rescued from a campervan by fire crews from Colchester and Wivenhoe fire stations.

The two casualties remain in hospital receiving treatment for their injuries following the incident, which saw both sides of the A12 closed for about four hours.
