The latest performance of Magic Goes Wrong was cancelled after a 'suspicious package' forced evacuation of the theatre.
Audience members at the Vaudeville Theatre as well as nearby restaurants were told to leave by police at around 7:20PM tonight (Saturday, January 11).
The mystery item that caused it all was ultimately deemed to be safe by officers.
A spokesperson for the Met Police said: "Police were called at approximately 19:20hrs on Saturday, 11 January to reports of a suspicious item in commercial premises on The Strand.
"Officers attended and the building was evacuated as a precaution. A number of local roads were also closed to traffic.
"The item has been found to be non-suspicious and cordons are in the process of being lifted."
The official Magic Goes Wrong Twitter account shared: "Tonight’s performance of Magic Goes wrong has been cancelled, due to circumstances beyond our control. Please contact your point of purchase to rearrange your tickets for an alternative date."
Magic Goes Wrong is the latest production from the Mischief Theatre Company who specialise in comedies where nothing ever goes to plan.
And that led to some audience members thinking that the very real evacuation was a part of the show.
Twitter user @AsforAlex posted: "We just got evacuated from @magicgoeswrong at the vaudeville theatre but no one moved at first as we thought it was part of the show...came outside to a police cordon. 😬"
Antoher person shared on Twitter: "As it literally happened as the show was about to start, no one moved, and we thought it was part of the show. It wasn't. 😩"
