Prosecutors disclosed new details Monday about last week’s stabbing aboard a Muni bus in SoMa, saying the victim was attacked after stepping between two women and a man they were telling to get away from them.

Glenn Hopkins, 44, of San Francisco, has been charged with attempted murder in connection with the Sept. 23 attack. The victim was taken to a hospital with life-threatening injuries, but District Attorney Brooke Jenkins said Monday that he is recovering and is expected to survive.

The stabbing occurred on a Muni bus near 10th and Mission streets. Mission Local previously reported that police responded around 1:41 p.m. Hopkins was arrested nearby and booked in the San Francisco Jail later that evening.

Jenkins said that the victim intervened after hearing the two women tell Hopkins to get away from them and stop staring at them.

According to court documents described by Jenkins, Hopkins continued trying to get past the victim but was unable to do so. He then allegedly pulled out a box cutter with its blade exposed and repeatedly swung it at the victim’s neck and throat.

Prosecutors charged Hopkins with attempted murder, assault with a deadly weapon against a public transit passenger, use of a deadly weapon and allegations of causing great bodily injury.

Jenkins said Muni surveillance cameras captured the incident and that the footage will be part of the prosecution’s evidence. She said Hopkins did not display the box cutter until after the victim intervened.

Hopkins is scheduled to be arraigned Monday at 1:30 p.m. at the Hall of Justice. Jenkins said prosecutors will ask a judge to keep him in custody while the case proceeds, arguing that he poses a public-safety risk.
