PLANO, TX HOOTERS ATTACKED BY YOUTHS IN CRAZY

1:17 PM PT — Plano PD tells TMZ … witnesses say this group of guys was selling chocolate in the Hooters parking lot, and when they were approached by a manager and asked to leave — things allegedly got violent. We’re told a couple of them attacked the manager and left with him a broken arm, and at that point … things spilled inside, where a customer was hurt too.

PPD says they’re investigating this as an aggravated assault case … but so far, no arrests have been made. They’ll be looking at this video as part of the evidence.

A Hooters in Texas came under intense assault this week — with a group of youths going crazy on the establishment and their customers … supposedly, because of some candy.

Video from the altercation first surfaced on Thursday — when the incident appears to have happened — but started making the rounds this weekend … and the footage is absolutely wild. You see a bunch of young guys, some of whom are shirtless, losing their minds.

They’re beating up what appear to be patrons in the vestibule of the restaurant … wailing on one guy in particular who falls to his knees. Some of the employees — including at least one Hooters girl — also seem to get roped into the action … with complete chaos unfolding.

One person filming says something to the effect of … “all over chocolate,” and you even see a chocolate bar on the ground at one point. Welp, as it turns out — that’s exactly what allegedly sparked this whole thing … according to a Hooters manager who spoke to TMZ.

We’re told these guys are door-to-door salesmen and that they came around that night trying to hawk their goods, only to be turned away over a no-soliciting policy Hooters has — which is apparently what set them off.

There weren’t more details provided, but the Hooters manager says they’ve resumed business and that a criminal investigation is ongoing.
