Surveillance video from the hotel shows 22-year-old Tehronn Greene beating the hotel manager, severely injuring him, according to police.

Police spokesman, Officer Ernesto Rodriguez told CBS4’s Peter D’Oench, “It was nothing short of brutal. I asked the detective who lead the investigation and he said he was troubled by this video. He said the victim deserved every last bit of investigative efforts provided so that the suspect could ultimately be arrested.”

Greene, who was at the hotel with a group of people, reportedly became angry when the manager asked them to leave.

According to the arrest warrant, they were asked to leave “because it appeared as if the room they had booked was reserved using a fraudulent credit card.”

Rodriguez said “One of the men jumps over the front desk counter and goes into a secure room where the employee was and begins to beat him. Again it is 35 seconds of video that is difficult to watch. Our investigators work tirelessly the last few weeks and where they were able to arrest Greene. It was a remarkable investigation where detectives utilized social media and a variety of tactics leading to this very important arrest.”

The people with Greene agreed to leave, but “Greene became enraged and jumped the counter viciously attacking (the) victim,” according to the warrant.

Police tracked down Greene in Norristown, Pennsylvania and he reportedly admitted to being the man on the video.

Greene will soon be extradited to South Florida where he’ll be charged with burglary with assault or battery.

Meanwhile, a 2nd person has been arrested in an attack on a front desk clerk on Tuesday at the Clinton Hotel at 825 Washington Avenue. Police say Mandy Calara, the owner of the VooDoo Lounge reportedly went to the front desk clerk to get a key to a friend’s room but the clerk refused to give it to him because Calara was not a guest.

In bond court on Tuesday, a Prosecutor said “The defendant went back behind the front desk and struck the victim and tried to take the victim’s cell phone. The defendant also struck the victim with a closed fist.”

The prosecutor also said Calara also tackled the victim outside the hotel.
