Fire crews were also called in to assist the police at the scene last night.

Ian Matthews, crew manager from Bolton North Fire Station, said: "We made our way down to the river wearing our water PPE and carried out a survey of the car to make sure no one was inside.

"There was around six to 12 inches of water flowing through the river.

"The car looked like it must have dropped or rolled onto its roof.

"It seemed as though both occupants were going to be relatively ok.

"We left the scene to police who were arranging the car's removal. But it would have been difficult due to the position of the drop."
