Police are blocking off part of the Leatherhead Road through Chessington because of an incident believed near Lidl.

Police cars have cordoned off a bus stop on the A243 road heading towards Hook from Chessington World of Adventures.

An eye-witness said: "They have got riot vans there as well.

"I saw two guys on the floor near Lidl but there was no emergency services by them.

"One man was lying on his side being attended to by a girlfriend or a friend.

"Another was holding a bandage to his head.

"I guessed the guy on the floor was quite badly hurt. He didn't seem alert like the other guy.

"The emergency services were by the Barwell estate. I don't know if they were looking for someone. They turned around and they went to the guy on the floor.

"Even now there's still police cars and undercover cops going down there."

Chessington councillor Andrew Day said: "It seems to be serious. There are a lot of police cars and a Transport for London van. Nobody is saying anything.

"It does not appear to be a traffic incident."
