Tory Lanez can get pretty turnt during his shows. Sometimes to the detriment of his personal safety.

But it was the safety of the crowd that was at issue during Lanez's show in Midlands, Texas Saturday night.

Lanez was apparently pissed off about the venue's security, so he encouraged the crowd to "fuck shit up."

Witnesses tell TMZ the concert then turned into a "WWE battle royal" with chairs, tables, bottles and other foreign objects being tossed about.

The cops swooped in and made multiple arrests. Now both the promoter and venue are threatening to sue Lanez for inciting a riot.
