A man has been arrested following the fatal collision that claimed the lives of two teenage boys on Wednesday evening.
A 22-year-old local man has been arrested on suspicion of causing death by dangerous driving and causing serious injury by dangerous driving.
He has since been released on police bail whilst enquiries continue.
The incident occurred on the A61 between Busby Stoop and Carlton Miniott in Thirk, North Yorkshire at around 9.25pm on Wednesday.
The horrific crash involved a green VW Bora which the man who has been arrested was driving and a black Ford Focus that were heading in the opposite direction towards Thirsk.
Two 17-year-old boys, George Turner and Mason Pearson, were rear seat passengers in the VW Bora, were sadly pronounced dead at the scene by paramedics.
Another two passengers in the same vehicle, an 18-year-old man and a 17-year-old boy, remain in a critical condition in hospital.
The driver of the Ford Focus, a 27-year-old man from outside the area, was discharged from hospital following treatment.
A passenger in the car, a 24-year-old woman, is receiving treatment at the hospital. A three-year-old girl and a six-month old boy have also been kept in hospital for observations as a precaution.
Following the fatal collision, Inspector Dave Barf from North Yorkshire Police Roads Policing Group, said: “A 22-year-old local man has been arrested in connection with the investigation and released on police bail while enquiries continue.
“The circumstances of the terrible collision which occurred on 7 March in which two young men lost their lives and others have been seriously injured, has inevitably been the subject of much comment and speculation on social media.
“The irresponsible spreading of information, which potentially has no basis in fact and may seriously prejudice the investigation, must be avoided.
“Anyone with information should contact the police and not commit it to social networks, where it only serves to cause additional distress to the families concerned and frustrate the investigation.”
The arrest comes as it is revealed that one of the firefighters, David Brown, 47, who attended the fatal scene, was the father of Daniel Brown, a boy who was left seriously injured.
Speaking of David and Daniel, a neighbour has described them as “a fantastic family”.
The family live in a four-bed semi-detached property in Thirsk and Daniel attended Thirsk High School and Sixth Form College, just 200 metres from his home.
The family were by Daniel’s bedside hospital Friday, neighbours confirmed.
A next-door neighbour, who wished to remain anonymous, said: “It is obviously a difficult time for them - they haven’t been back to the house since it happened.
“They’re with Daniel in hospital.
“It’s horrible to think that David was called out to this crash doing his job and his son was involved.
“Hopefully Daniel will pull through, the family are fantastic and a really loving, caring set of people.”
He added: “I don’t know how serious Daniel’s injuries are.”
Officers are continuing to appeal for people to come forward to assist the investigation, including witnesses to the actual collision, anyone who recalls seeing any of the vehicles involved prior to the incident, and anyone who may have dash-cam footage that could help with enquiries.
