Paul Tam, 48, a website manager who had moved from Manchester to Los Angeles for work, was killed during a street robbery in San Francisco. He was walking with his niece on Post Street between Franklin and Gough when a couple attacked them to steal his messenger bag. Video shows Tam trying to hold onto the bag, backing into the street and attempting to run around a car; the male suspect tackled him in the roadway and stabbed him in the head. Tam’s niece was not injured and was taken for treatment; Tam died on March 24 at San Francisco General Hospital.

Police say the robbers took the bag, which reportedly contained his passport, money, mobile phone and bank cards. The suspects are described in release sketches as a black adult male, about 5 feet 10 inches, heavy build, wearing a dark hoodie and blue jeans; and a black adult female, about 5 feet 4 inches, with long dreadlocks or braids up in a ponytail. The San Francisco Police Officer’s Association is offering a US$5,000 reward for information that leads to an arrest.

Does anyone have information about that couple or saw the incident on Post Street that day?
