British tourist stabbed in San Francisco mugging dies

A British tourist who was stabbed in the head during a robbery in San Francisco died after being hospitalised for more than a month, police said.
Paul Tam, 48, of Manchester, died on Thursday at San Francisco General Hospital, where he was taken after the February 18 attack, said San Francisco Police Officer Albie Esparza.
Tam was walking with his niece when he was attacked by a couple. Tam tried to hold onto his messenger bag but was stabbed in the head by the male suspect, Esparza told the San Francisco Chronicle.
His niece, who is from Southern California, was not injured, San Francisco Police Officer Carlos Manfredi said.

Security video released Friday by police shows the attacker chasing Tam onto a street, stabbing him while he's on the ground and taking his bag before running away.
"As he is going around the vehicle he falls down, it's at that point that the suspect not only wanted to take the victim's bag, but he wanted to take his life," Manfredi told San Francisco television station KGO.
Police have yet to make an arrest in the attack, which is now being investigated as a homicide.
The San Francisco Police Officer's Association is offering a USD 5,000 reward for information leading to the arrest of the two suspects.
