A teenager has been arrested on suspicion of dangerous driving after three cars were involved in a horror crash in Rathfriland, Co Down.
Two men - James Annett and Gary Elliot, both thought be around 20-years-old - were taken to Daisy Hill hospital following the serious collision on the Banbridge Road at around 9pm on Tuesday.
Mr Annett was transferred to the Royal Victoria Hospital where he is on a life support machine.
Last night, a spokeswoman for the Belfast Trust said Mr Annett remained "critically ill".
Mr Elliot, a close friend of Mr Annett, remains in a stable condition at Daisy Hill Hospital.
UUP councillor Elizabeth Ingram said the entire community was shocked.
"It's a difficult time for all the families, especially the Annett family," she said.
"I know them very well. They are farming people and well-respected in the area.
"Everyone is hoping and praying James can manage to make a good recovery.
UUP councillor Glenn Barr is friend of the other injured man, Gary Elliot.
He said a ramp on the Banbridge Road had been removed some time ago as some drivers used it as a takeoff point to try and make their car airborne.
"This crash has been a shock for the entire town," Mr Barr said.
"Gary's family are with him. I believe he was injured by smashed glass but he's doing well and is going to be okay. My thoughts are with the other injured young man and his family.
"The Banbridge Road is quite a speedy road. I would urge young drivers in particular to exercise caution and take care when driving on it."
A police spokeswoman said the 17-year-old male arrested has been released on bail pending further enquiries.
Meanwhile, on Wednesday morning there was another serious crash on the Largy Road near Portglenone.
The Largy Road was closed at the junction with the Ballynafie Road and motorists were asked to avoid the area .
The Ballynafie Road reopened last night.
