The two victims were struck shortly before 2 a.m. at the intersection of Van Ness and Pacific Avenues, San Francisco police spokeswoman Sgt. Lyn Tomioka said.
"It appears that the victims may not have been in the crosswalk at the time," Tomioka said.
One of the victims, a 28-year-old San Jose man, suffered injuries that were considered life-threatening, Tomioka said. The other victim, a Vacaville resident, also 28 years old, suffered minor injuries.
It was not clear how fast the driver was going, Tomioka said.
The driver continued on for a block and got stuck behind other vehicles at the next traffic light. Witnesses pulled him out of his vehicle and detained him until police arrived, Tomioka said.
The suspect, Giovinder Avilez, was booked on two felony counts of hit and run, and one count of driving under the influence, according to Tomioka.
