A man has been arrested after two teenagers were found dead at a holiday park in east Yorkshire.
Police were called to Little Eden Holiday Park in Bridlington on Wednesday, where a 15-year-old girl and a 17-year-old boy were found dead inside one of the rental properties.
A 33-year-old man was arrested on Thursday on suspicion of gross negligence manslaughter and remains in custody, police said.
Chief Superintendent Matt Peach of Humberside Police said: "Whilst we are in the very early stages and the deaths at this time remain unexplained, we are exploring the possibility that they may be connected to carbon monoxide poisoning, with further enquiries continuing with our partner agencies."

Mr Peach said a cordon remains in place, adding police are "working closely with Humberside Fire & Rescue, the Health and Safety Executive, and East Riding of Yorkshire Council to establish the full circumstances surrounding the incident".
He said: "This is incredibly distressing and heartbreaking for the families of the teenagers involved, and they are at the forefront of our minds and actions.
"Specially trained officers have been supporting the families over the last 24 hours, and I would please ask people to refrain from any form of speculation and to respect their privacy.
"We have a dedicated team conducting extensive enquiries, some of which have been complex and required additional time to complete."
