A taxicab was stolen near San Francisco State University early Friday morning and the suspect then led authorities on a pursuit to Pacifica and back, a San Francisco police spokesman said.
The cab was parked at Denslowe and Banbury drives around 1:15 a.m. when the driver got out to help a sick passenger, police spokesman Officer Gordon Shyy said.

The suspect took that opportunity to get into the driver's seat and drive off, Shyy said.
Police spotted the taxi around 2 a.m. and the suspect drove off. A low-speed pursuit began that headed onto southbound Interstate Highway 280, according to Shyy.
Daly City police and the California Highway Patrol took over the pursuit, which headed into Pacifica before the suspect turned around back to San Francisco, Shyy said.
The stolen taxi eventually stopped near San Francisco State, where the driver abandoned the vehicle and fled on foot.
Campus police and the CHP searched the area, but the suspect eluded arrest, Shyy said.
During the pursuit, the cab hit property near San Francisco State, causing minor damage, according to Shyy.
No one was injured during the carjacking and subsequent chase, he said.
Investigators searching for the suspect are reviewing surveillance video, including footage captured from the inside the cab, Shyy said.
