South San Francisco police have arrested a San Francisco man on multiple charges stemming from "an ongoing inappropriate sexual relationship with a minor" that took place from 2009 to 2012.

Brandon Hamm, 37, a San Francisco resident, was initially arrested June 22 on charges related to child pornography and other allegations.

Then, Tuesday, June 26, South San Francisco Police Department detectives contacted Hamm at the San Mateo County main jail, where he's currently being held on $400,000 bail. A department news release issued today (Monday, July 2) says the case involves "solicitation practices involving social media."

San Mateo County District Attorney Steve Wagstaffe said in an interview Monday that the "very serious" charges against Hamm include 41 felony counts stemming from the June 26 arrest. More than half of those are for engaging in a lewd act with a minor. He said some of the charges are related to someone under the age of 16, while others are for a minor under the age of 18. That indicates the charges involved contact with the same person over a period of time, he said.

Wagstaffe said the charges for the June 22 arrest include felony counts of arranging for a meeting for the purpose of committing a lewd act with a minor, communicating with a minor for commission of a lewd act, sending pornography to a minor by email, and a misdemeanor charge of arranging a meeting with a minor for a lewd act.

Ryan McHugh, Hamm's attorney, declined to comment on the case.

A preliminary hearing is set for August 6.

Hamm was recently a volunteer clergy member at Peninsula Metropolitan Community Church in San Mateo. A church official told the Bay Area Reporter that his MCC license is now inactive.

It's not clear whether Hamm identifies as gay, but as of Saturday, June 30, his Facebook page said he was in a relationship with another man. That page appears to be inactive as of Monday morning.

Anyone with information related to this case is encouraged to contact the South San Francisco Police Department, Criminal Investigations Unit at (650) 877-8900.
