Police in Minneapolis have arrested more than a dozen suspected gang members, some as young as 13, accused of preying on drunk people and robbing them of their cellphones and valuables in a series of violent attacks.

One of the incidents took place on August 3 at the Target Field plaza and was captured on surveillance video.

The graphic recording shows a gaggle of about 12 teenagers and young men surround two men playing a game of dice on the sidewalk.

About 40 seconds into the video, one of the ruffians appears to snatch a man's cellphone. The victim shows resistance, prompting one of the attackers to throw the first punch.

From there, the violence quickly and dramatically escalates.

After going through his pockets, the perpetrators proceed to repeatedly punch the victim, kick him in the head and stomp on him.

While the man is lying supine on the ground, several of the assailants jump on him, and one of them body-slams the man.

The footage shows the attackers ripping the victim's shoes and pants off, and trying to remove his boxer shorts.

The victim is seen in the video cowering and trying to protect his head with his hands from brutal blows raining down on him.

Towards the end of the footage, one of the most aggressive attackers, who is dressed in a light-blue shirt, hurls a potted plant at the victim, before another youth runs him over with a bicycle.

The video ends with the muggers walking away from the scene, leaving the victim standing in his underwear.

By the time police responded to the plaza, all the suspect as well as the victim had left.

Then on September 6, police recognized one of the suspects from the video and arrested him.

Boris Likuwa Lusmbo, 20, allegedly admitted that it was him in the footage taking part in the violent robbery. He has been charged with first-degree aggravated robbery and faces up to 20 years in prison, if convicted.

Another suspect in the video was identified as Adrian Jamal Cooper. The 25-year-old at first denied playing part in the attack, but later allegedly admitted to hitting the man for calling him a 'b****,' and boasted that the victim was 'not that strong.'

On August 29, police tracked down a third suspect matching one of the attackers seen in the footage. Antonio Kolli Morrow, 21, allegedly told detectives he took the victim's wallet from another suspect, and then slipping it into his own pocket.

Further examination of the CCTV footage led to another suspect, Jamar Shamar Robinson, 20, who has been charged with first-degree aggravated robbery and third-degree riot.

The complaint states Robinson admitted it was him in the video, but denied hitting the victim. He also said he did not steal anything, even though the video showed the 20-year-old striking the victim twice and stuffing something in his pocket.

In all, police arrested 16 suspects believed to be members of a loosely organized gang targeting intoxicated people for their cellphones and wallets.

All the alleged perpetrators, ranging in age from 13-25, were apprehended in the course of a three-day sting operation two weeks ago. Have of them are juveniles.

In another incident, on August 17, a man told police he was out with friends at a bar in downtown Minneapolis when he was robbed and assaulted. He claimed he didn't remember much of the incident because he lost consciousness.

According to a criminal complaint, the victim said he was standing on a corner using his phone when a group surrounded him and tried to take his wallet. He said he lost his iPhone and his wallet, which contained his driver's license, debit card, keys and $100 in cash. He also was notified by his bank that $220 was withdrawn at an ATM using his debit card.

After beating the thugs knocked the man unconscious, they fled, leaving him lying motionless on the ground, according to the compliant.
