COLUMBIA, MO. -- A 19 year-old Columbia man is behind bars after police said he had child porn on his computer and was sharing them with others.

Police arrested Anthony M. Thompson Friday morning at his home without incident.

Last month investigators seized his computer and said they found a large number of files containing child pornography.

Some of the illegal images and video depict the sexual molestation of children as young as 7 to 8 years- old.

Thompson is in the Boone County Jail awaiting formal charges.
