A 17-year-old girl is in a critical condition after she became tangled in a noose at a Halloween haunted house.
Police said the girl, who was working as an actress at the attraction in St Louis, Missouri, was found unconscious with the prop around her neck.
The girl is thought to have fallen off a bathtub at Creepyworld where she had been working for two weeks.
It is thought that members of the public may have walked past her thinking she was a scary prop.
She was discovered by a colleague who was checking on the safety of employees at around 8:30pm last night.
Captain Ron Arnhart of the Jefferson County Sheriff's Office said: 'We noticed a bathtub was there. It appears as though the individual stood up on the sides of the bathtub and for whatever reason, put their head in this noose.
'It looks like her feet may have slipped,' he told local station KTVI. 'It looks like an unfortunate accident.'
A Creepyworld spokesman said: Our only concern is that she's going to be OK. That's all we care about.'
The attraction, which employs 100 people, has remained open.
