AUSTIN (KXAN) — One man involved in demonstrations in downtown Austin over the weekend is in critical condition following an incident with police, according to Austin Police Chief Brian Manley.

Around 11 p.m. Sunday, a 20-year-old man, recording with a phone, was hit in the back of the head by a less lethal round, Manley says. The incident was captured on downtown Austin’s HALO camera system — which is designed for APD to monitor potential events in the downtown district.

Manley says a person next to the victim reportedly threw a water bottle at officers near the stairs of APD headquarters. The person was subsequently seen throwing a backpack toward the officers. At that moment, Manley says one of the officers fired a less-lethal round and it hit the victim instead.

Manley believes the victim hit his head as he fell.

“I’m crushed. I’ve cried a few times. One (person), at least, is fighting for their life,” Manley said during a Monday news conference. “This is not what we set out to do this weekend. It’s tough right now. This is something we are taking very seriously.”

A second protester was also seriously injured by another, less-than-lethal round, according to Manley. APD opened investigations into several incidents of officers injuring protesters in Austin.

Austin police said officers arrested almost 30 people related to protests in the past 24 hours on charges including burglary, theft, interference with public duties, graffiti, engaging in organized crime, assault and participating in a riot.

Manley says there will not be a curfew in Austin at this time, but leaders will continue to evaluate the situation. Manley is expected to brief Austin City Council on Thursday regarding APD’s response to the protests.

Fifteen officers were treated for minor injuries during the weekend events. One officer was transported for stitches, according to Manley. He says officers did not fire any live rounds.

My nephew should be at the academy in Austin right now but was delayed because of some Austin hippie stuff. I hope to God he rethinks this career choice.

I'll say this again, when I was growing up in FW in the 50's looters were shot DEAD on the spot. We also had shotgun squads that would stake out convenience stores. If you came to rob you were shot DEAD. Little bit of that goes a long way to quell any looting or robbing.

Yes, but then you expect people to be responsible for their actions. You expect people to realize decisions have consequences. Surely you realize we have advanced way beyond such barbaric tactics. Surely you are not advocating personal responsibility. What’s wrong with you? Common sense? Really? That’s almost unAmerican today.

I can’t be more sarcastic without the use of vulgarity. Lol
