A skilled pickpocket who performed on Britain's Got Talent this evening (April 18) left the judging panel speechless within moments of stepping onto the stage.

Lee Thompson, from Birmingham, had crafted a polished routine in which he repeatedly lifted Ant and Dec's phones, glasses and room keys without them noticing.

He was also shown covertly planting wristwatches in the bags and pockets of audience members after posing as a security guard in a pre-recorded segment - even managing to get backstage with the judging panel, including Simon Cowell.

Yet barely moments after first stepping out onto the stage, he left Amanda Holden in particular completely gobsmacked, as he revealed his true age.

"You look very dapper," Amanda remarked as the performer first walked out. He swiftly replied: "Oh! Do I look my age?", reports Wales Online.

"I don't know, how old are you babes?" the judge quipped, as Lee then confessed: "I'm touching 60."

His revelation left Amanda visibly astounded as she shot back with a "You're not! Are you?" in sheer disbelief. Simon, clearly equally impressed, then added: "You look good."

Following their initial exchange, he went on to dazzle the entire panel with his act, earning himself the title of the "modern-day Artful Dodger" from Amanda.

Remarkably, Lee was actually employed as a Pickpocket Consultant on Guy Ritchie's Young Sherlock series on Prime Video, which follows a young Sherlock Holmes as he finds himself trying his hand at pickpocketing after being inspired by the story of Oliver Twist.

Viewers at home were equally taken with the performer, with one writing: "This is genuinely amazing. Even if he might be incriminating himself." A second enthused: "That was clever, funny and amazing....good job."

While Lee sailed through to the next round with four yes votes from the panel, some viewers questioned why he wasn't awarded the coveted Golden Buzzer, which grants an act a direct passage through to the live final.

Fans were outraged this evening after KSI awarded a contentious act his Golden Buzzer. Comedy act Mr Cherry, 44, kicked off his performance by opening a jar of pickles before subsequently uncorking wine bottles with his buttocks.

"Ladies and Gentlemen, I don't know about you but that was the greatest thing I have ever seen," KSI declared, as disgruntled viewers swiftly branded his choice the "worst Golden Buzzer" act ever put through on the programme.

Britain's Got Talent airs Saturday nights from 7pm on ITV1 and ITVX. All episodes can be streamed on ITVX after broadcast.
