A WOMAN has been found dead in what is reportedly a “chemical ” incident at a hotel in London.

Witnesses have reported the hotel and neighbouring restaurant being evacuated and chemical response teams on the scene.

One witness told Daily Star Online everyone staying at the hotel has been “quarantined”.

She said: “My husband has just been advised by police that they found someone dead with unknown chemicals.

“Until they figure out what they are they can’t give any more information.”

Eight police cars, six fire engines and eight embulances are on the scene – as well as officers in hazmat suits.
