TRENTON, N.J. (AP) — A former Rutgers University instructor has pleaded guilty to using a university computer to share child pornography online.

Gary Swiatek faces up to five years in prison and will be permanently barred from public employment when he’s sentenced in February.

State prosecutors say the 49-year-old former biochemistry instructor on the Rutgers Cook Campus in New Brunswick used peer-to-peer file sharing technology.

He was arrested at his home in Hillsborough in January.
