An 'unwanted guest' crashed the Britain's Got Talent 2018 live shows tonight.
This evening saw the second live semi-final of the new series.
And towards the end, one member of the audience decided to crash the judges' desk.
After illusionist group Magus Utopia performed, the random person ran up to the judges' panel and began to hit the buzzers before being taken away by security.
Host Dec was quick to say: "Apologies for our unwanted guest, some people just want to touch the buzzers."
Simon Cowell remarked: "It's going to be one of those nights."
A video shared on Twitter by @scubasteve1414 said: "What a take down! Take a bow mr security man #BGT #BGTSemiFinal"
Alongside Magus Utopia, tonight's live show saw performances from David Walliams' golden buzzer, singer Donchez Dacres, choir B-Positive Choir, singer Calum Courtney, impressionist Andrew Lancaster, singer Ronan Busfield, dance group Futunity and comedian Nick Page.
This evening's issue of human interference followed last night's technical problems that saw the show end up off air for almost 15 minutes.
Just moments after Cali Swing performed first, the signal went out.
A screen on ITV and a voice over blamed 'technical issues'.
Instead of the live show, the channel began to show highlights of auditions.
After around 10 minutes, the show returned live to the Hammersmith Apollo with host Dec blaming the weather in London for the signal problems.
Simon Cowell quipped: "Ant, you'll be back next year, you didn't have to do that."
In the semi-finals, which air all this week, eight of the top 40 acts will perform live in the hope of impressing viewers at home and winning the all-important public vote.
Two acts from each night’s show will make it into the live final on Sunday 3 June, with a chance of winning a life changing £250,000 and a spot at this year's Royal Variety Performance.
