San Francisco police detained a woman in connection with a Monday incident in the Bayview neighborhood in which a 63-year-old woman died after being pushed to the pavement. 

Police sources said investigators spotted the suspect, 42, around 10:30 a.m. Thursday and detained her near Third Street and Egbert Avenue, the same corner where the alleged attack occurred earlier in the week.

Yanfang Wu, a city resident, was getting off a Muni bus around 6:40 p.m. when the suspect pushed her violently to the pavement, causing her to hit her head, police said. Authorities are investigating the case as a homicide. 

Wu was rushed to a hospital, but police said Tuesday evening that she had died. 

Police said the suspect, who has a prior criminal history, fled the scene following the attack. She was set to be booked into San Francisco County Jail on suspicion of a manslaughter-related charge, but authorities said the exact charges would depend on the circumstances of the case, including accounts from witnesses.

San Francisco police say officers have investigated 27 homicides so far in 2023, up slightly from the same time last year. In mid-May, the Bayview witnessed a fatal shooting at the corner of Third Street and Palou Avenue, and the neighborhood logged separate fatal shootings last Saturday and last Tuesday.

Correction: An earlier version of this article incorrectly stated that the suspect was arrested; she was detained.
