Two people were carjacked after their vehicle was flagged down by four men in Potrero Hill early Tuesday, police said.
The victims, a 21-year-old woman and 30-year-old man, stopped the car after one of the thugs flagged them down at 25th and Dakota streets around 2 a.m., police said.
One of the carjackers pulled out a gun and demanded their property. The victims handed over a cellphone.
The thugs then stole the car and fled, police said. The car was later found unattended.
No arrests have been made.
