A Lincoln firefighter and substitute school bus driver for the public school system has been charged with possession of child pornography.

The Associated Press reports, Lincoln police arrested 52-year-old Daniel King after an investigation revealed a computer at his home had been used to download child pornography in December.

Court documents indicate investigators found other files consistent with file sharing and child pornography on the computer and external drive.

King is expected in court on Feb. 7.

He was a substitute school bus driver for Lincoln Public Schools since 2009. School officials say they removed King from the list of possible drivers.

The city’s public safety director says King is on leave from the fire department.

King’s attorney did not immediately return a phone call placed Saturday afternoon.
