MENLO PARK, Calif. — A former youth swim team photographer arrested last month on suspicion of molesting boys has been charged with sexual assault in Northern California after authorities say six more alleged victims came forward.

Randolph Haldeman was arrested Wednesday at his Menlo Park home. He’s facing 20 charges, including sodomy and committing lewd acts on a child, according to a San Mateo County Sheriff’s Office website.

He’s being held on $5 million bail. It’s unclear whether he has an attorney.

Haldeman photographed a swim team that practiced at a Portola Valley recreation center. Authorities contend he molested boys as young as 6 years old.

He’d been free on bail since his July arrest. At the time, authorities said three people alleged he molested them as far back as the late 1980s.
