Tenacious D Concert Shut Down After STABBING In The Audience!

What on EARTH is going on with people these days?!

This is the LAST place something like this should have happened!

The Tenacious D concert at Mandalay Bay's House of Blues in Las Vegas had to be shut down unexpectedly last night after a huge fight broke out in the audience, which left at least one person hospitalized for STAB WOUNDS!

According to reports, Jack Black and Kyle Glass were in the middle of their set when the altercation started in the crowd. It's unclear what exactly went down, but one individual was stabbed in the leg, but is expected to recover. Authorities have confirmed, meanwhile, that they have one person in custody and they are not on the look-out for any other suspects at this time!

Ugh! Such a terrible shame!
