A group of three teenagers beat and robbed a Sunset District pedestrian last week, but as of Monday the knife-wielding miscreants remain at large.

The San Francisco Police Department alerted media to the crime this Monday: A group of three males aged 17-18 attacked a 16-year-old as he walked down a busy Sunset District street, threatening him at knifepoint and stealing his possessions.

Police say that the victim was walking near Ulloa Street and Sunset Boulevard when he was approached by the three suspects at 9:30 p.m. last Wednesday.

According to the SFPD, one of the teens "pulled a knife" and threatened the victim. When the victim tried to flee, a second suspect tripped him, causing him to fall to the ground.

A third suspect held him down, as the first two went through his pockets and stole his belongings.

All told, the teens absconded with the victim's wallet, his cash, he cell phone, and a portable charger. They also left him with non-life-threatening injuries, police say.

The suspects fled on foot following the crime, and haven't been seen since. As of Monday afternoon, police confirm that the larcenous trio remain at large.
