A 16-year-old girl is in a critical condition after being found unconscious outside a gym and near a busy main road.
The teenager is believed to have collapsed between 9.30pm and 10.45pm yesterday in the grounds of Everton Park Lifestyles gym on Great Homer Street, Liverpool.
She is now in a critical but stable condition in hospital, the Liverpool Echo reports.
Today a cordon remained in place in the area, which is opposite the Sainsbury's supermarket and another gym complex, The Gym, which is open 24 hours a day.
The Gym's assistant manager Norbert Telek said he arrived for work early this morning to find a large cordon in place outside.
