A former Lawrence resident was indicted in federal court Wednesday on charges of failing to register as a sex offender.

Robert Frederick Baker, 47, was serving federal probation in Kansas for a previous violation of registering as a sex offender when law enforcement discovered Baker had left Kansas without notifying the proper authorities. A federal arrest warrant was issued for Baker, who was arrested in Oregon, according to court documents.

In 2010, Baker, living in Lawrence, was a suspect in Feb. 9, 2010, stabbing in the 1300 block of New Hampshire Street. Assault charges against Baker were dropped in that case, but Baker was charged and convicted with failing to register as a sex offender in Kansas.

Baker — whose original conviction was in 1995 in South Dakota for sexual abuse of a child — served 14 months in federal prison on the failing-to-register conviction. Baker was released in March 2011, and was serving his probation in Kansas before he left the state in 2011 without notifying authorities, according to the indictment filed in the U.S. District Court of Kansas.

Baker faces up to 10 years in prison if convicted.
