AUSTIN -- Austin police and Austin ISD police have made one arrest and are searching for another man in connection with two videos of fights on YouTube.
In a video posted last week, four teenagers can be seen engaging in a violent, but consensual, fight less than half a mile away from Crockett High School. Two of the students are wearing Crockett High School football shirts and police say there are dozens of Crockett High students standing around watching the fight.
At the end of the video, a 17-year-old Austin ISD student is on the ground, arms up blocking his bloody face as a different 17-year-old repeatedly punches him then stomps on his head.
"If any incident takes place, it's a problem. And we address it as such," said Austin Police Detective James Stanesic of the Joint Juvenile Gang Intervention Unit. "We can't afford for the students or the community to be at risk."
When Austin police and AISD Police Joint Juvenile Gang Intervention Unit (JJGIU) started investigating, they found that on March 20th at about 3 a.m., a teenager was spotted painting gang graffiti on a Crockett High School portable building and an employee's car.
"The staff member gave chase, the individual ran off from the campus," said AISD Police Chief Eric Mendez.
One week later, the video of the students fighting was posted on YouTube. Police officers say the teenager seen stomping on the head of another boy is the same one that tagged the school. Police are now looking for him.
Wednesday, officers arrested 23-year-old Roman Flores for aggravated assault with a deadly weapon. He was seen in the fight video wearing all black, yelling and throwing gang signs. Police say the day after the fight happened, there was a second fight that was also posted online.
"There were adults fighting and toward the end of the video, you see the suspect pull out a knife, which it wasn't used on anyone, but just the display of the knife in conjunction with the fight we were able to obtain the warrant," said Detective Lance Cox of the JJGIU.
Police are still investigating the involvement of the other students in the video and say the best thing parents can do it talk with their kids.
"I would urge parents to tell their children don't go and watch as much as you want to, as much as you think it's something interesting to see, because those situations can become volatile, those situations can become deadly," Chief Mendez said.
The detectives say this was not a gang fight, but the two men just happen to be gang members. The man they are still searching for is not enrolled in school.
Officers also want to stress that the fights and graffiti should not be seen as a reflection on Crockett High School. And that they don't consider it to be a problem school.
As for the young man who was beat up in the video, police say is doing well.
