A man who was released from a US prison 90 years early due to a clerical error has returned to serve the rest of his sentence.

Rene Lima-Marin, of Colorado, was free for nearly six years due to the mistake. He had a child, married his former girlfriend and held a job. But a prosecutor noticed the mistake in January, and a judge immediately ordered Lima-Marin back to prison.

A judge in 2000 sentenced Lima-Marin to serve back-to-back sentences on eight convictions, for a total of 98 years. But a court clerk mistakenly wrote in his file that the sentences were to run at the same time.
