An overzealous fan was caught on video groping Nick Jonas during his concert in Los Angeles earlier this week.

In a video captured by a concertgoer, the fan can be seen grabbing at Nick’s legs, butt and crotch during the Oct. 21 event. Security tried numerous times to stop the fan from touching the 27-year-old crooner, but she continued to grab him anyway, according to the video. Eventually, Nick turned around and appeared to scold the audience member before resuming his performance.

Fans on Twitter expressed their anger and disappointment at the unknown groper, with one supporter writing: “They need to stop touching him PERIOD!”

“This probably ruined his whole night,” wrote another. “It’s never okay to sexually assault someone, let alone in front of literally thousands of people??”

“This is honestly so hard to watch. Can they not get it through their heads that Nick is clearly uncomfortable as he turns back to look at them and tried to swat their hand away?” noted another. “Ugh, this is not how you should treat them. Theyre people just like us who don’t need to feel violated.”
