A San Francisco mom doesn’t need a police lineup to point out the creepy little thug that robbed her — it was her son, police said.

The 17-year-old allegedly pushed his mom, swiped her iPhone and fled Wednesday, treating his flesh and blood like any other helpless robbery victim.

The 48-year-old mom called police around 8:45 p.m. Cops responded to the 700 block of Foerster Street, near the Sunnyside neighborhood, and interviewed her. The mom claims she’d gotten into an argument with her son before he robbed her, police said.

The suspect fled. No arrests were reported Thursday.
