Federal prosecutors say a New Jersey child protective services worker is facing child pornography charges.

Trent Collier, 55, had returned to the United States on Tuesday aboard a flight from the Dominican Republic. When authorities searched his luggage, they say they found a tablet computer and cellphone. Prosecutors say at least two images of child porn were discovered on his phone.

Collier works as a caseworker for the state Department of Children and Family Services.

He was released on a $50,000 unsecured bond after he made his initial court appearance.
