COLORADO SPRINGS, Colo. — A Colorado man sent to prison for more than 300 years for child sex assault but released early is back behind bars.

The Gazette reports 46-year-old Michael McFadden was arrested in Colorado Springs on Friday for failing to register as a sex offender in a separate case.

The Grand Junction Daily Sentinel reports he was released from prison Tuesday after the Colorado Supreme Court declined to consider a lower court’s ruling that his right to a speedy trial had been violated. McFadden was convicted in 2015, but his trial was delayed after his attorneys sought to include provisions in the juror questionnaire and the judge granted a continuance.

He was previously convicted of child sex assault and was required to register as a sex offender. Booking documents don’t indicate if McFadden has an attorney.
