OAKLAND -- Two reputed gang members were charged Friday with robbing and pistol whipping a player and some spectators at an adult soccer game Wednesday night in the Fruitvale district, authorities said.

Mario Caballero-Sanchez, 19, was charged with one count of robbery and three counts of assault with a firearm. Kenneth Byrd Jr., 19, was charged with one count of robbery and one count of assault with a firearm. Both are from Oakland.

The violence happened about 8:40 p.m. Wednesday at a soccer field in the 1600 block of Fruitvale Avenue where members of a female adult league were playing.

Police said the suspects had been disrupting the game and making disparaging remarks toward the players.

A referee and some parents tried to get them to leave and they responded with violence, police said.

A 29-year-old player from Hayward was beaten with a gun the men had that turned out to be a replica and was robbed of her phone, credit cards and other items, police said.

A 58-year-old Castro Valley man who was watching his daughter play was hit with the gun as was a third man, police said.

The suspects fled the park but were stopped and arrested by police a few minutes later near 34th Avenue and Farnam Street. Some of the items taking from the player were recovered as was the replica gun, police said.
