A 21-year-old volunteer coach for a Sunnyvale girls’ volleyball team was arrested for sending harmful matter to two 13-year-old girls, police said Sunday.

Sunnyvale resident Moises Martin was arrested at his home Friday on suspicion of one felony count of sending harmful matter to a minor and two misdemeanors of annoying and molesting a minor, said Capt. Shawn Ahearn of the Sunnyvale Department of Public Safety.

Incarcerated in a Santa Clara County jail, Moises was released on bail by Sunday, jail records show.

An initial victim Friday morning told the principal of her Sunnyvale school what had happened, causing police to launch an investigation, Ahearn said. The police captain declined to name the school, citing the privacy of the victims.

Moises was arrested later that day.

The victim had evidence that Martin had “made inappropriate comments to her via social media,” Ahearn said.

Martin knew both victims from coaching the after-school volleyball team at a recreation center in north Sunnyvale, Ahearn said. He declined to name the center to maintain the privacy of the victims.

Police Sunday were still investigating and left open the possibility that there could be additional victims.

“We already have two victims,” Ahearn said. “There is a possibility that there will be other victims.”
