Around 8:50 p.m. Tuesday, officers stopped a 2008 Honda Civic at Vicente Street and 36th Avenue. During the traffic stop, the 17-year-old driver opened the glove box and an illegal dagger allegedly fell out.
Officers conducted a search of the vehicle and discovered a loaded assault weapon in the truck, police said. The male driver was booked on reckless driving and possession of a gun. The male juvenile passengers, all city residents, were detained and released.
About 12 hours later, officers were searching a vehicle in the 1000 block of Fitzgerald Avenue around 9:10 a.m. Wednesday when they recognized one of the passengers.
Police said 25-year-old Ramon Thornton, who was sitting in the passenger seat of the 1998 Buick Park Avenue, was on active felony probation and was arrested for possession of a gun when police found a handgun on the driver's seat.
Then at about 6:10 p.m. Wednesday, officers responded to Osceola Lane and La Salle Avenue on a report of shots fired. They stopped a speeding 1993 Dodge carrying two males, who told police that two suspects were firing at them.
Officers located the two male suspects, identified as San Francisco resident Gerardo Canon, 18, and a 17-year-old San Francisco boy, and a handgun in the 1200 block of Oakdale Avenue. The teens were charged with carrying a concealed firearm, carrying a loaded firearm and conspiracy.
Officers also arrested 20-year-old Robert Ramey, a San Leandro resident who was in the van. The three males arrested also face gang enhancement charges.
Later, at 9:45 p.m. Wednesday, police responded to another report of shots fired at Brookdale Avenue and Santos Street. Officers arrested two 17-year-old San Francisco residents and seized two handguns and another assault weapon found in a nearby trashcan.
