San Francisco police on Jan. 24 announced that they had arrested a second suspect connected to a violent Chinatown robbery back in July that left two men injured.

On Jan. 22, officers arrested 20-year-old Akeem Smith of Sacramento on suspicion of battery, assault, robbery and elder abuse.

Smith was already being held in Alameda County on related charges, according to jail records.

Back in October, police arrested a different suspect in connection with the July robbery. Oakland resident Dashawn Pierson, 19, was taken into custody on Oct. 22 on suspicion of robbery, assault, battery and elder abuse.

While serving Pierson’s arrest warrant, officers located items connected to the robbery, police said.

The robbery happened at 1:09 p.m. on July 15. Officers initially responded to Stockton Street and Pacific Avenue after someone reported a robbery there.

Officers determined that three suspects had picked up a 56-year-old San Francisco man who had the watch on and threw him to the ground. The second victim, a 69-year-old San Francisco resident, tried to intervene and the suspects knocked the person unconscious.

Both victims were taken to a hospital for head injuries and have since been released, police said.

Although two suspects have been apprehended, a third suspect remains at large.

Anyone with information about the robbery is asked to call the Police Department’s 24-hour tip line at (415) 575-4444 or text a tip to TIP411 and start the message with SFPD. Tipsters can remain anonymous.
