Four people - including two teenage girls - have died following a fatal collision between a sports car and a quad bike close to Doncaster.
The incident happened about 10 miles to the north of the town in the early hours of this morning on the A6201 between Upton and Hemsworth in West Yorkshire.
Officers were called at about 12.34am today to a report of a collision between a bronze Nissan 350z sports car and a quad bike.
It is believed the Nissan had been travelling towards Hemsworth on the A6201 when it came into contact with and was in collision with the rear of the quad bike.
Two women and a man on the quad bike were confirmed earlier today to have died at the scene as a result of the incident.
Police have now said a second man has also died.
More details have been released about those who have lost their lives.
Two females aged 18 and 16 and a 20-year-old male on the quad bike were confirmed to have died at the scene as a result of the incident.
A second 20-year-old man was taken to hospital with critical injuries to his head and body. He died earlier this morning at Leeds General Infirmary.
Two men aged 21 and 22 from the Nissan were arrested on suspicion of dangerous driving in connection with the collision and remain in police custody.
