The death of a 53-year-old man who was assaulted on a Tenderloin sidewalk is under investigation as a homicide, police said Tuesday.

Kevin Driscol, of San Francisco, has been identified by the Medical Examiner’s Office as the man who was assaulted last Friday afternoon on Ellis Street between Jones and Leavenworth streets.

Police were flagged down at the scene and medics rushed Driscol to the hospital, where he later died from injuries related to the assault, according to Officer Robert Rueca, a police spokesperson.

The Tenderloin Police Station said on Twitter that a suspect was arrested in the Tenderloin on Monday and booked in connection with the homicide.

Rueca declined to release information about the person in custody.

The death marked the 40th homicide reported in San Francisco in 2018.
