The Guardian Angels helped a 21-year-old man in the Mission district who was being beaten by robbers Friday night, police said Monday.
The victim was reportedly walking in the 2700 block of Mission Street when four thugs attacked him about 10:20 p.m. They put the man in a headlock, dragged him to the ground and punched him while swiping his smartphone, police said.
But then members of the Guardian Angels, a volunteer public-safety group, shooed off the suspects.
The victim suffered swelling to his forehead but is expected to survive, police said.
