OAKLAND — A registered sex offender with a long history of molesting children has been arrested and charged with possessing more than 100,000 images of child pornography, authorities said Thursday.

Davey Hudson, 55, was arrested Nov. 7 at his Oakland home and charged two days later by the district attorney’s office with multiple counts of possession or control of child pornography and activity involving material depicting sexual conduct.

The Oakland police Vice and Child Exploitation Unit, with the help of the FBI, conducted an investigation that led authorities to Hudson.

A search warrant at his home in Oakland, led to the recovery of more than 100,000 child pornography images from a computer he owned, police said.

According to state records, Hudson lived in the 500 block of Foothill Boulevard in the Eastlake district.

In a statement, police said the department is dedicated to prevention, enforcement, community education and partnerships in such cases and will continue to work with other agencies to combat human trafficking and the sexual exploitation of children.

According to state records, Hudson has prior convictions for lewd or lascivious acts with a child under 14 and annoying or molesting a child under 18 and has served at least one prison sentence.

The lewd conduct conviction was in 1998 in Contra Costa County and involved an 11-year-old boy whose genitals were fondled, according to state records. Hudson was the boy’s roller-hockey coach, the records say. A search of Hudson’s vehicle at the time found papers downloaded from the internet concerning false child abuse allegations and a list of instructions on what to do if one is accused of child molestation, the records say. He was put on probation after a county jail term.

In 2001 he was convicted in Santa Clara County of two misdemeanor counts of annoying or molesting a child under 18 — the victims were two young boys who lived next door to him. He took pictures of the boys and put them on his computer, and also placed his hands on the boys’ shoulders while they played video games on the computer, the records say. He was sentenced to prison and eventually paroled in 2005.

According to the records, Hudson unsuccessfully challenged a condition of his parole that restricted his computer and Internet access, and his access to camera equipment.

Hudson, who listed his occupation in jail records as “engineer”, is being held in lieu of $200,000 bail in Santa Rita Jail and is due in court Jan. 31 for a pre-trial hearing.
