POLICE officers are appealing for witnesses following a large vehicle overturning on a busy roundabout last night.

Emergency services flocked to the A137 after a highway maintenance vehicle fell onto its passenger side on the Harwich Road roundabout.

A police and fire crew arrived at the scene shortly before 9pm last night as concerned onlookers gathered to watch on.

An update issued by an Essex Police spokesman this morning stated the force is continuing to appeal for witnesses and individuals with dash cam footage to come forward.

He said: “We were called just before 9pm last night to reports of a single vehicle collision in St Andrews Avenue.

“Emergency services attended the scene of an overturned lorry. Road closures were in place until around 1.30am but all roads are now reopened.

“We’d like to speak to anyone who was in the area at the time and saw the collision or anyone who may have dash cam footage to contact us.”

Simon Crow, the county councillor for Parsons Heath and Eastgates, stopped at the scene just after 9pm.

He told the Gazette: “I couldn’t see what the cause of it was, but there were lots of people standing around at the scene.

“There are police and a fire crew and there seems to be fluid coming out the back of the vehicle.”
