The former Oakland Police Officer who was arrested in March in Polk County for a sex crime involving a 2-year-old girl faces additional charges after forensic evidence revealed child pornography on his cellphone and in his email, deputies said Thursday.

Joshua Smith, who was a member of the Oakland Police Department, in Orange County, for nine years was arrested at his home in Lakeland earlier this year and charged with directing or promoting the sexual performance of a child.

After Smith was arrested, the State Attorney's Office added two other charges (possession of a photo depicting sexual performance by a child and lewd molestation).

Smith, 33, was charged with an additional 11 counts of possession of child pornography. The State Attorney's Office added the charges after forensic examinations of his emails and cellphone revealed additional images containing child pornography.

The images don't appear to be related to the original images found during Smith's arrest in March, Polk County detectives said.

Smith has been in the South Polk County Jail, in Frostproof, since his initial arrest. He now faces a total of 14 charges.

He was initially placed on administrative leave with pay, but Oakland Police Lt. John Peek confirmed Thursday that Smith resigned shortly after his initial arrest.
