Sometimes all it takes to make a huge difference is for one person to speak up. That's exactly what happened when Sam Carter, the lead singer of the metal band Architects, stopped his show and called out a man who sexually assaulted a female concert-goer in front of him.

"I saw a girl, a woman, crowd-surfing over here, and I'm not gonna f*cking point the piece of sh*t out that did it, but I saw you f*cking grab at her boob," Carter said during his performance at the Lowlands Festival in Biddinghuizen, The Netherlands, on Friday night.

"I saw it. It is f*cking disgusting and there is no f*cking place for that sh*t," he declared. "It is not your f*cking body. It is not your f*cking body and you do not f*cking grab at someone. Not at my f*cking show."

Carter's speech was met with applause from the audience and was later uploaded on to Twitter [1] by the Dutch public radio channel NPO 3FM. Although the 28-year-old singer admitted he was cautious about speaking out at first, Twitter users were quick to commend him for doing so. "[T]hank you for saying something, it makes me so happy to see that people are talking about this issue [2] instead of ignoring it," one person tweeted [3] to the singer.

Hopefully Carter's actions will inspire other brave musicians to call out sexual assault [4] at their concerts when they see it. Watch the powerful moment as it unfolded ahead.
