Updated at 6:30 a.m. Friday: Revised to reflect that a suspect has been arrested and to include comment from the Trump campaign.

Note: A version of this article included quotations from a man who said he saw teenagers at a San Antonio restaurant before a hat was stolen. KENS-TV, which first reported the man's words, has withdrawn the specific comments "due to concerns about the legitimacy of the statements."

A mother's Facebook video post that has gone viral shows a man tossing a drink at her son and his friends and claims he did so because one of the teens wore a "Make America Great Again" hat at a San Antonio Whataburger.

A suspect in the case, 30-year-old Kino Jimenez, was arrested Thursday night in Universal City, according to KENS-TV in San Antonio. He has been charged with theft, San Antonio police said.

The man stole the hat bearing the slogan of President Donald Trump and ripped out a few of Hunter Richard's hairs Wednesday before he walked away, the 16-year-old told KENS-TV.

Hunter said he filed a police report. San Antonio police have not responded to a request for comment.

"This is going to go great in my [expletive] fireplace, [expletive]," the man says as he walks away.

"All right, have fun with it," one of the teens responds.

Hunter said he wishes the man had just talked to him about their differences in politics.

"I support my president, and if you don't let's have a conversation about it instead of ripping my hat off," Hunter told the television station. "I just think a conversation about politics is more productive for the entire whole rather than taking my hat and yelling subjective words to me."

The woman who posted the video, Patricia Spittler, asked for help identifying the man, who she called "scumbag of the year."

"His friend was wearing a patriotic hat, and this happened! It would be nice to know who he is for someone to let him know his actions are not okay! Real tough guy ... approaches a group of teenagers minding their own business just having a burger! He kept his hat, too," Spittler wrote in her original Facebook post, according to KCEN-TV in Temple.

The Facebook video has been changed to a private setting, but it was also posted on YouTube.

The person who posted the video on YouTube says the man who threw the drink should be deported. There is no evidence the man is in the country illegally.

Whataburger released a statement Thursday saying no employees witnessed the incident.

"We were shocked to see this video and certainly don't condone this type of customer behavior in our restaurants," the statement said. "To be clear, no Whataburger employees were involved or witnessed the incident, and we ask that questions be directed to San Antonio PD as we continue supporting their efforts."

Brad Parscale, Trump's campaign manager, said in a tweet that he would like to offer Hunter an autographed hat.

"I would love to send this teenager a signed @realDonaldTrump hat and stand with him in #SanAntonio," Parscale tweeted. "There are hundreds of thousands that will stand with you there. Don't let a few left bullies stop you from showing your #MAGA!"
