Teen trouble down by the SF Maritime Museum on Saturday, as a group of teens ganged up on and walloped a man who admonished them to slow down on their bicycles, and then they tried to rob him, but bystanders shooed the teens away.

A situation with unruly teens on their bicycles turned scary on Saturday afternoon, as KTVU reports that a group of minors beat and robbed a man on the 900 block of Beach Street in Fisherman's Wharf, near the SF Maritime National Historical Park. The attack reportedly occurred at around 2:50 pm Saturday, and was initiated, of all reasons, because the man apparently told the teens to slow down on their bicycles.

"A preliminary investigation revealed that the victim observed multiple juveniles on bicycles and attempted to advise them to slow down," the SFPD said in a statement to KTVU. “One suspect then battered the victim, which led to a verbal confrontation between the victim and juveniles. The verbal confrontation turned physical as the suspects began to batter the victim who attempted to flee."

Somehow, the victim was already receiving medical attention from paramedics by the time police arrived on the scene. There is no update on the victim’s current condition, nor whether any of the injuries from the assault were serious.

The teens did steal a bag from the victim, which he attempted to retrieve after it was tossed onto the street. If it reaffirms your faith in humanity in any way, police say the teens all fled the scene "after being confronted by bystanders."

Anyone with information on this incident is asked to call the SFPD tip line at 415-575-4444, or text a tip to TIP411 and begin the message with “SFPD.” Tipsters can remain anonymous.
