A 51-year-old man was making a transaction at an ATM near Civic Center early Wednesday when a man shoved a gun against his lower back and demanded money, police said.
The incident happened at Golden Gate Avenue and Polk Street around 12:30 a.m., police said. The unknown gunman was accompanied by another man.
When the victim felt the gun pressed against his back, he gave up an undisclosed amount of cash and his debit card.
Both thieves fled. Detailed suspect descriptions were not released.
