A San Francisco man who was kind enough to offer a stranger in need some cash near Hallidie Plaza last weekend was punched, robbed and strangled, police said.
But with help from a merchant, the 25-year-old reportedly managed to pin down the robber until officers arrived.
The incident unfolded about 1:35 p.m. Sunday in the area of Cyril Magnin and Market streets. The victim was walking down the street when an unknown man approached him and asked to borrow cash, Office Gordon Shyy said.
"The victim pulled out some money, and the suspect grabbed it and ran," Shyy said.
The man chased after the suspect and caught up to him inside a store in the 100 block of Eddy Street. The victim told the clerk to call 911 and then demanded his money back, Shyy said.
The suspect, identified as 52-year-old Berkeley resident Frederick Chisom, allegedly punched the victim several times in the face and strangled him. The clerk helped to restrain Chisom, Shyy said, and kept him down until officers arrived.
Chisom was booked on robbery and assault with a deadly weapon charges and also had an outstanding warrant out of San Francisco, according to police.
The victim suffered a black eye and scratches on his neck during the ordeal but declined medical attention, Shyy said.
