A criminal couple remains on the loose Wednesday, following a mugging in SoMa that left its victim shocked and bruised.

Police say that the 59-year-old male victim was attacked and robbed at 9 p.m. Monday at the intersection of Fourth and Bryant Streets.

According to the San Francisco Police Department, the man was approached by a male and female suspect, who "then tased him 19 times." Stunned and unable to fend off the robbers, the victim says the duo took his wallet, which contained cash and his identification.

The victim was bruised in the attack, and was transported to San Francisco General Hospital with injuries police say are not life threatening. The Taser-wielding couple fled on foot, and haven't been seen since. As of Wednesday morning, police say, no arrests have been made in this case.
