Authorities have filed another 90 charges of possession of child pornography against a Martin County man who blamed the crime on his cat.

According to a sheriff's report, Jensen Beach resident Keith Griffin told investigators that pornographic images downloaded when his cat jumped on his computer keyboard while he was downloading music.

Griffin was arrested in early August and charged with 10 counts of possession of child pornography. Investigators filed the additional charges on Thursday.

Griffin is being held in lieu of $2.2 million bail at the Martin County Jail. He was not immediately known if he has an attorney.

Sheriff's officials said a family friend was caring for the cat.
