A man wanted on an attempted murder charge has been arrested after pulling up next to a police car and talking a swig of an alcoholic beverage, authorities said.

Police officers witnessed the driver of a four-door, silver, Volkswagen vehicle pull up beside the police vehicle at a stop light at the intersection of Third and Oakdale streets.

The driver was drinking from an open container of an alcoholic beverage as he waited for the light to change.

Officers conducted a traffic stop and determined that the driver, Christopher Chiquillo, 19, of San Francisco, did not possess a valid driver's license.

San Francisco police searched Chiquillo and recovered a silver handgun and several rounds of ammunition, police said.

Upon further investigation, Chiquillo was also found to have been involved in a domestic violence incident on Sunday, in which he had fired shots at a victim using a silver handgun, police said.

Chiquillo was arrested for possession of a prohibited weapon, domestic violence, traffic violation and attempted murder, according to police.
