Tekashi 6ix9ine might’ve faced an even more brutal beatdown if it weren’t for the quick-thinking gym staff that rushed in to get him to safety after he was ambushed in a sauna.

It’s a bummer for 69 … especially since our sources say he’d actually frequented this gym quite a bit in the past without any issues. We’re told he’s normally in there for about 20 minutes, and sticks to the StairMaster … minding his business.

Our sources tell us if Tekashi is ever approached or recognized, most of the interactions are peaceful … and he’s usually accommodating and willing to pose with fans. Of course, he’s clearly got enemies out there — no doubt still lingering from the infamous RICO case.

Despite his past, we’re told the consensus in this case thus far is … Tekashi did nothing wrong and didn’t deserve this.
