SAN FRANCISCO - Police in San Francisco arrested a 19-year-old Daly City man on suspicion of murder for a brazen attack last week on an 84-year-old man in the city’s Anza Vista neighborhood, officials said Sunday.
San Francisco police arrested Antoine Watson on Saturday after serving a warrant at a home in Daly City. He was booked on suspicion of murder, elder abuse and assault with a deadly weapon.
Officers also arrested 20-year-old Maylasia Goo on suspicion of being an accessory after the fact.
Security video shows a fatal attack on an 84-year-old man in San Francisco's Anza Vista neighborhood.
The victim was identified by family members as Vicha Ratanapakdee, a native of Thailand who lived in San Francisco.
The attack happened around 8:30 a.m. Thursday. Paramedics responded to the scene and found the victim lying on the sidewalk at Anzavista and Fortuna avenues, police said.
Security video of the incident captured by a neighbor and shared with KTVU show a man barrelling into the victim before taking off running.
Paramedics rushed Ratanapaddee to a hospital where he succumbed to his injuries two days later.
Investigators later recovered the video of the attack and determined the assailant had fled with a female associate, police said.
A tactical unit served the warrant and arrested Watson and Goo at a home on the 500 block of Lisbon Street in Daly City around 8:45 p.m. Saturday.
Anyone with information about the case was asked to call police at 415-575-4444.
