Staind frontman Aaron Lewis launched into an expletive-ridden rant on stage at a concert in Kansas City on Saturday, admonishing members of the crowd for touching a girl he said looked about "15 years old".

The band were halfway through the ballad Something To Remind You when Lewis cut his chorus short and shouted:

"Alright, listen up, you f***ing a**holes," Lewis began after stopping the show in the middle of a song. “That f***ing girl right there is, like, 15 f***ing years old, and you f***ing pieces of s**t are molesting her while she’s on the f***ing crowd."

"Your f***ing mothers should be ashamed of themselves you pieces of s**t.

[Video has strong language, obviously]

"You should all be f***ing beaten down by everyone around you for being f***ing pieces of s**t. If I f***ing see that s**t again, I swear to god, I will point you out in the crowd and have everyone around you beat your f***ing a**."

The rant was met with cheers from the crowd, and while encouraging violence was not very responsible, the inappropriate touching did seem to stop after the dressing down.
