A MYSTERY vehicle spilled diesel and left a trail of havoc on a Huddersfield road.
The vehicle had leaked the diesel on Dalton Bank Road from Colne Bridge to Dalton yesterday afternoon.
Seven vehicles ended up damaged as they ploughed into one another after skidding on the slippery surface.
The road runs behind the giant Syngenta plant off Leeds Road.
Sgt Andy Addy, of Huddersfield traffic police, said: "No-one was hurt, but we shut the road from Colne Bridge to Dalton as a precaution.
"Drivers were able to go the other way by driving with extreme care. The rain had hardly helped the situation.
"We would like to speak to anyone who may have seen the vehicle which left the diesel on the road surface."
