Warrington teenager death: 'Illegal substance' inquiry
A 16-year-old girl has died after reportedly suffering breathing difficulties at a house in Warrington.
Emergency services were called to Densham Avenue, Longford at about 03:30 BST. Despite efforts from paramedics, Ellie Jones died at about 05:00.
Police said they were investigating the possibility she may have taken an "illegal substance".
Officers confirmed Ms Jones did not live at the house, but was there with four other teenagers.
Supt Martin Cleworth, from Cheshire Police, said inquiries were focused on establishing her movements during the evening prior to her death.
He said: "Our investigations into the cause of her death are at an early stage, and I would appeal for public help and support in progressing these.
"I would also like to reiterate the message, and to young people in particular, around the dangers of taking any illegal substance."
A post-mortem examination is due to take place.
