LOCKPORT – A Level 1 sex offender who allegedly left the state without permission pleaded not guilty to a two-count felony indictment in Niagara County Court Thursday.

Derrick J. Houser, 26, whose last registered address was on Cedar Avenue in Niagara Falls, is charged with failure to report a change of address and failure to disclose all his Internet identifiers. Both are required under New York’s Sex Offender Registration Act, Assistant District Attorney Robert A. Zucco said.

Houser was extradited after being found in Michigan in September, Zucco said. He’s being held without bail in the County Jail.
