Police arrested 13 people after motorists on the M25 were pelted with the proceeds of an egg factory raid.

Dozens of eggs were broken, or stolen, at the Tadworth factory some time between 11.30pm and 11.45pm on July 19.

Three women aged 17, 18 and 19 from Sutton, Surbiton and Epsom, and 10 men, aged between 16 and 21 from Epsom, Carshalton, Sutton, Malden, Morden and Surbiton were arrested after the break-in on Tuesday, July 19, between 11.30pm and 11.45pm.

Police said five cars arrived at the factory, down a single lane track, and began smashing windows at the egg-sorting warehouse.

Once inside, they took a number of trays of eggs.

The intruders began throwing eggs at the building before making off along the track.

When police arrived two vehicles attempted to escape but collided with each other.

Some of the eggs had been thrown over a nearby motorway bridge between junctions nine and eight of the M25.

The group were all arrested on suspicion of burglary, criminal damage and endangering road users.

Senior investigating officer, Detective Sergeant Glenn Parker, said: "We have a lot of work to do to unravel exactly what happened at the farm.

"Although it’s a rural location I am appealing to any motorists who were travelling on the M25, between junctions 9 and 8 around the time of the offence, who may have seen eggs being thrown onto the motorway, or their vehicle was hit by an egg, to come forward.

"It is not yet clear precisely how many eggs were damaged during the burglary but several dozen trays, each containing 30 eggs, were removed.

"I appeal to anyone who has any information regarding this incident, no matter how small it may seem, to come forward.

"The victim has spent many years building up their business and we will work hard to ensure those responsible are brought to justice."

All those arrested have been released on bail until September.
