Two of Texas' 10 Most Wanted Fugitives were arrested last week, including a Spring man who has been wanted since 2006.

Gwen Komahcheet, 62, of Spring was arrested Thursday by authorities in Piedras Negras, Coahuila, Mexico. DPS officials said Komahcheet had a violent criminal history that included sexual assault, and he had been wanted since 2006 for parole violation and failure to register as a sex offender.

He was arrested as a result of a tipster, who was awarded $7,500.

Komahcheet was added to the list in early 2012 after he violated parole on a conviction of aggravated rape with a firearm and failing to register as a sex offender. He has a record dating back to the 1960s. He was arrested in Oklahoma in 1969 for creating a disturbance. He then traveled to California, where he was arrested for robbery. In 1972, he was arrested for rape in Oklahoma. In 1975, he was arrested in California for drunken driving, assault with a deadly weapon and disturbing the peace. In 1979, he was arrested in Dallas for sexual assault with a deadly weapon. He received a 75-year sentence but was released on parole in 2004 after serving 24 years.

Charles Edward Robertson-Davis, 22, a member of the Bloods gang, was arrested in Austin Wednesday. Investigative leads and surveillance led authorities to him. He was wanted for parole violation and obstructing police, evading arrest.

In 2013, DPS and other agencies have arrested 12 of Texas' 10 Most Wanted Fugitives and Sex Offenders, including four gang members, and $17,500 in rewards have been paid for tips that resulted in arrests. The cash rewards are funded by the Governor's Criminal Justice Division.
