A Denver police officer shoved a Colorado Rockies fan at Coors Field on Tuesday, prompting an internal investigation into allegations of excessive force.

Alex Buck, a 22-year-old fan, says the Denver cops, including Capt. Joe Black, confronted him over suspicions of underage drinking, NBC affiliate KUSA reports. A video of the encounter begins as Black asks Buck to sit down in a chair.

When Buck refused, Black shoved him down into the chair on three separate occasions, prompting the fan to accuse him of excessive force. “Officer, that is abuse. ... Officer, you have no constitutional right to physically force me to sit down,” the young man said.

Eventually, Buck was placed in handcuffs. However, he told KUSA, he was not charged with any crime.

Matt Murray, the Denver Police Department’s chief of staff, confirmed that authorities would investigate the incident, but declined to provide additional details. “We’re investigating and that’s it,” he told the Denver Post. “We care about this. We’re going to do the right thing.”

The department took to Twitter on Thursday to assure citizens that it would thoroughly investigate the incident captured in the video.

“COMMUNITY: We want everyone to know that Chief (Robert) White 'hears' your concern about the recent video involving DPD. He is closely monitoring the investigation and will share the results with everyone when appropriate," department officials said in the tweets. "If the investigation results in a violation, then the officer will be held accountable. Thank you for your patience and understanding as we investigate.”

A video of Buck’s confrontation with police went viral this week, generating more than 100,000 unique views on YouTube. Deadspin identified Buck as “Rockies Bro.”
