The Imax cinema at the Science Museum was evacuated today ten minutes into a showing of Star Wars: Episode VIII - The Last Jedi.

The museum located in Kensington, West London, confirmed that 'part' of the site had been evacuated as a precaution.

But it was later claimed to have been a false alarm, with cinema-goers allowed to re-enter the Imax to continue with the film.

Tom Vincent tweeted: 'Just been evacuated from the Science Museum Imax due to an 'incident'. Oh dear. Nobody seems to know what is going on.'

He later added: 'A very helpful security guard from Science Museum is keeping the group I'm in up to date re: evacuation. Thank you.'

Jim Reed said: 'Watching Star Wars at Science Museum and just stopped ten minutes in to evacuate everyone in building because of an 'incident'.'

Charlie Fry added: 'Love it when you're watching the new Star Wars at the science museum but get evacuated because of an 'incident'.'

And Jocelyn Le Conte tweeted: 'Just been evacuated from the 4pm showing of Star Wars at the Imax screen. What's the process for refunds and rebooking?'

A Science Museum spokesman tweeted: 'We've evacuated part of the museum as a precaution. The team are just investigating what's happened now.'

They also told Ms Le Conte: 'Once the museum reopens if you go to one of the ticket desks they'll be able to give you a refund or book you for a different screening.'

Laura Pritchard said later: 'Well done Science Museum, getting audience back into screening of Star Wars Last Jedi after fire alarm interruption. Great communication.'

Jim Reed added: 'Science Museum evacuation was false alarm. Swift work from people working there to get everyone out though.'

Tickets for watching the new Star Wars at the museum's cinema on the Imax 15/70mm 2D film format start at £16.50 for adults.

The screen at the museum is almost double the size of those found at large cinema chains - the height of four double-decker buses or a car park for 64 taxis.
