A custody battle involving a Pleasanton man has led to criminal charges against an Alameda County deputy sheriff and a San Ramon attorney and an investigation involving a Pleasanton police officer.

Brian Lancaster has filed a claim against the city of Pleasanton asking for in excess of $1 million. Lancaster said the actions of the three led to him losing his job and custody of his kids. Three misdemeanor charges have already been filed against Deputy Ryan Silcocks and Lesley Regina, a San Ramon family law attorney.

Silcocks "was charged and is on administrative leave," said Alameda County Sheriff's Spokesman J.D. Nelson. He said the charges involve "inappropriate accessing information off a computer and providing that information."

The deputy allegedly entered a court building after hours on two occasions, accessed documents, and forwarded them to Regina, whom he was dating. Regina, who represents Lancaster's ex-wife, Lisa Secord, who lives in Washington state, has been charged with one count of knowingly receiving records that she was not authorized to possess.

Lancaster said the Pleasanton police are conducting an investigation into the actions of Officer Tim Martens.

"I allege the same thing was done between Tim Marten and my ex-wife," Lancaster said. He said Martens, who was in communication with Secord, later arrested him on a drug possession charge, then forwarded confidential information to be used in the custody case.

"It says right on the stuff, 'This is confidential information, do not share with anybody,'" Lancaster said.

Pleasanton City Attorney Jonathan Lowell confirms a claim has been filed.

"We are investigating it," Lowell said. He said he couldn't comment further on an active case.

No charges have been filed against Martens; Silcocks and Regina are set to be arraigned July 9 on the misdemeanor charges.

Lawrence said he'd worked as operations manager for a construction company for 14 years before losing his job as a result of the actions of the three involved.
