There are a number of casualties after a balcony collapsed during a packed performance at London's Apollo Theatre.
Around 30 people are injured, according to Sky News.
The extent of the injuries is unclear, but some injuries appear to be minor. A London Fire Brigade spokesperson has told reporters that all those who were trapped have been freed.
The balcony collapsed around 8.15pm during sold out performance of "The Curious Incident Of The Dog In The Nighttime." 775 can be seated at the Soho venue.
Witnesses told BBC that the ceiling in the theater crumpled and caved in. Onewitness said there was "complete chaos" in the theater after the collapse, telling Sky News: "At first we thought it was part of the show. Then I got hit on the head."
Apollo Theater was built in 1901 and has four levels, according to BBC.
