Police cameras that captured the beating and robbery of drunken man in a downtown parking lot earlier this week helped lead officers to the suspects.

Cameras positioned above a parking lot under Interstate 4 recorded a group of men attacking another man as he sat near a parked car early Monday.

The cameras are part of a larger network of police surveillance equipment keeping watch over Orlando.

One of the men stole an iPhone from the victim, who was knocked unconscious during the beating, police said.

An officer watching the live video at police headquarters helped alert officers on the street to the attack, according to newly released police documents.

Officers arrested Jeffrey Diaz, 22; Jean-Marc Agnant, 22; and Raheem Burnside, 18, in connection to the attack. All three were charged with robbery. Diaz is facing additional charges of felony battery and grand theft, reports show.

Diaz told police that he and his friends were walking back to their car after spending the evening at Tabu Nightclub on Orange Avenue when he was heckled by the victim.

Diaz was trying to pick up a group of girls who "were not at all interested," the report said. "Diaz stated he became angry at the victim because he believed he [the victim] was making fun of him for being turned down by the girls."

Video of the incident shows one man, later identified as Diaz, "sucker punches" the victim in his head and the victim falls over. Burnside and Agnant look around the parking lot and Agnant tries the handle of the victim's locked vehicle. Meanwhile, Diaz rifles through the victim's pockets and takes the iPhone, reports show.

Afterward, Diaz and his two friends jumped inside the sport-utility vehicle and speed off. They were pulled over a short distance away and Diaz was arrested after admitting to hitting the victim, police said.

Less than a minute after the officer let Diaz's friends leave, another officer radioed that the victim had been robbed of his cell phone.

Officers pulled the group over again on I-4 and Conroy Road and searched for the phone. It was found wrapped inside a T-shirt inside of a plastic bag wedged between the backseat and the speaker box.

Burnside, Agnant and another man who was also in the SUV were arrested on robbery charges. After reviewing the video, the officer released that man because he didn't participate in the crime, police said.

The victim was transported to a local hospital where he was treated for several cuts and bruises. Four of his bottom teeth were pushed back at a 45-degree angle, reports show. His name was not released.
