A 48-year-old British tourist was pronounced dead on Thursday, more than a month after being stabbed in the head during a street robbery in San Francisco, police said.

Paul Tam died at San Francisco General Hospital, where he was taken following the Feb. 18 attack, officials said.

The incident began after the tourist, walking with his niece on the 1300 block of Post Street near Franklin Street, was attacked by a man and a woman about 8:30 p.m., according to authorities.Tam attempted to hold onto his messenger bag but was stabbed in the head by the male suspect, according to Officer Albie Esparza, a police spokesman.

The man’s niece, who lives in Southern California, was not injured.

Police released a security video on Friday that showed Tam resisting the attacker and running into the street in front of a car. The footage shows the attacker chasing Tam, stabbing him while he was on the ground and taking his messenger bag before running off.

Police have yet to make an arrest in the stabbing, which is now being investigated as a homicide. The suspected killer was described as being in his 30s or 40s and his female accomplice is in her late 20s.
