And the rampant robbery of cellphones goes on.

Two more people were robbed of their cellphones in San Francisco on Tuesday and early Wednesday morning, police said. The latest robberies were in the wake of District Attorney George Gascon’s call for major cellphone service providers to help stem the thefts.

The first robbery was at Bacon and Somerset streets about 9 a.m. Tuesday, police said. In that incident, a 23-year-old woman was standing on the corner when one of two 11- year-old boys grabbed her cellphone. The victim wouldn’t let go when the second boy threatened her, police said. The victim wrestled with the boy but he was able to snatch the phone and the two fled on foot.

The second cellphone robbery occurred Wednesday about 2:05 a.m. at Golden Gate Avenue and Van Ness, police said. In that incident, a 29-year-old man was walking along the street when three men in their 20s snuck up from behind and knocked the victim down.

One of the thugs grabbed his cellphone while the others demanded his cash, police said. The victim complied and the crooks fled on foot.

The victim complained of pain to his neck, but he refused medical attention. No arrests have been made in either case.

UPDATE: SFist reports that a personal trainer was attacked for his cellphone Monday night near 17th and Noe streets. Dalton Huckaby was assaulted and mugged around 9 p.m. He was talking on his phone when it was snatched from his hands by a man in a black-hooded jacket. When Huckaby gave chase he was attacked from behind and knocked to the ground by a second suspect. The story originally appeared on the Castro-area blog Castro Biscuit.
