POLK CITY, Fla. (AP) - Authorities say a 22-year-old Disney World employee has been arrested on charges of child pornography.

The Polk County Sheriff's Office says Timothy Wayne Hammerstone of Polk City worked at the commissary at Disney's Hollywood Studios.

Hammerstone was being held Sunday on 16 counts of possession of child pornography. Jail records did not show whether he was represented by at attorney.

Investigators say Hammerstone communicated with boys in California using his Xbox gaming system. One boy's mother contacted police after he sent naked photographs to Hammerstone.

Disney issued a statement saying Hammerstone no longer works for the company.
