A man died after being punched in the face on a San Francisco street, and his alleged assailant has been arrested, police said.

The attack occurred on the night of Sept. 28 at the Bernal Dwellings complex, near Treat Avenue and 26th Street in the Mission District. The 34-year-old man was with a group of people outside when another man punched him. The victim hit his head when he fell to the ground.

His companions took him to a hospital but did not report the assault to police.

Three days later, on Friday, the man died in the hospital.

Police investigators identified the suspect, a 32-year-old San Francisco man, and he turned himself in on Monday night.

He has been booked into jail on suspicion of murder and failure to register as a sex registrant, police said.

The victim’s name has not been released.
