Police are appealing for witnesses after five teenagers where injured following a road traffic collision in Accrington.
At around 11.30pm last night (Wednesday) a black Vauxhall Corsa was travelling northbound on the A56 easterly by-pass when it came off the carriageway, 500 metres north of the junction with Sandy Lane.
The car overturned and travelled a further 250 metres before coming to rest on its roof in lane two.
Two rear seat passengers, a boy aged 16 and a girl aged 17, and the male driver, aged 17, all suffered head injuries and were taken to Royal Blackburn Hospital where they are said to be in a serious condition.
The other two passengers, two 16 year old boys, suffered more minor injuries. They were also taken to Royal Blackburn Hospital, but were later released.
All the occupants are from the Accrington and Blackburn areas. The road was closed for around four and a half hours for accident investigation.
A second black Vauxhall Corsa was also driving along the same stretch of road at the time of the incident.
Sergeant Pete Sculpher said: "A full investigation into the cause of the collision is now underway. I would appeal to anybody who may have witnessed exactly what happened to contact police.
"I would also like to speak with anybody who may have seen either or both Corsas being driven along the A56 prior to the incident."
