Baltimore (CNN) -- Baltimore police say they made an arrest in a violent robbery in March that left a man battered and stripped of his clothes on a street while onlookers laughed and did nothing to help.
Police arrested Aaron Parsons, 20, Friday evening for his alleged involvement in the March 18 incident captured by cell phone videos that went viral nationwide. He faces multiple counts of robbery, theft and reckless endangerment, police said.
The victim was headed to his hotel from a downtown Baltimore club when he was attacked, according to a police report. The man, who had been drinking, told police he could not recall exactly what happened. However, the videos fill in the blanks.
In them, a man is seen standing unsteadily against a row of mailboxes. A crowd starts to gather and women dance suggestively against him. Someone notices his watch and a hand seems to grab something from one of his front pockets.
He pursues the supposed thief and is punched in the face. The man falls over backward and his head hits the sidewalk so hard it can be heard on the video.
"Smackdown!" someone yells.
His pockets are rifled and his clothes pulled off. Some people can be heard laughing, and no one comes to his aid.
According to the police report, the man lost his Tag Heuer watch, which he valued at $1,300, his iPhone and car key.
After the video went viral, authorities received multiple tips that Parsons was involved in the melee, a Baltimore police report said. Investigators also used Facebook and Parsons driver's license to help identify him, the police report said.
Police are searching for other suspects.
