DENVER (KUSA) - 9Wants To Know has confirmed that Felix Trujillo, 24, an inmate at the Denver Jail downtown escaped at 7 p.m. on Sunday evening.

A Denver deputy sheriff was arrested for assisting in the escape, officials announced Monday morning.

The Denver Police Department is looking into the incident involving deputy Matthew Andrews, 36, who is two-year veteran of the force. He was arrested during an investigation on assisting in an escape.

Deputy Andrews is out on bond. A formal decision on charges will come from the district attorney's office later this week.

Andrews has had run-ins with the law in the past. In 1998, he was booked into the Larimer County Jail for a misdemeanor warrant for illegal possession of alcohol.

The Denver Sheriff Department says Trujillo may be armed and should be considered extremely dangerous.

Major Frank Gale, with the Denver Sheriff's Department, told 9NEWS in an email, "He [Trujillo] may have a deputy's uniform jacket but does not have a radio or any officer's gun."

According to a Denver jail offender list, Trujillo was being held for aggravated robbery and a community corrections violation.

Trujillo has a lengthy criminal history in Colorado. 9Wants To Know investigative reporter Jace Larson has learned that Trujillio was charged with escape in Adams County in 2011 but plead guilty to attempted escape and was sentenced to six months in jail.

In August 2012, Trujillio was arrested for burglary with a weapon. He pleaded guilty and would have faced a sentence of 16 to 24 years on May 13.

Denver police are actively searching for Trujillo, who is described as 5 feet, 6 inches tall, weighing 140 pounds with tattoos on his neck and chest.

9NEWS reporter Kevin Torres reported seeing little police activity in the area around the jail at Colfax and Delaware at 10 p.m. Sunday.

Anyone with information regarding his whereabouts is asked to call 720-913-2000 or 911.
