THE AIR ambulance has been called to an 'ongoing incident' in Towyn.
There is a large emergency services presence at Ty Mawr Holiday Park.
North Wales Police says it is dealing with a "serious incident".
A spokesperson for Ty Mawr Holiday Park said: "We are shocked and saddened by this tragic incident.
"Ty Mawr is a 100 acre family park which welcomes tens of thousands of happy holidays makers every year. This was an isolated and unprecedented incident which took place inside a caravan which is now a crime scene.
"Our team are assisting police with their enquiries and as it is a police matter we can’t comment further at the moment."
Traffic on the A548 near the holiday park was said to be gridlocked and people are urged to avoid the area.

"Investigations are ongoing. Apologies for any disruption caused.
"There is no threat to the public but please stay away from the area whilst we deal with the incident.
Thank you for your patience."
