A Denver sheriff’s deputy has been arrested in connection with the escape of a prisoner who walked out of the county jail Sunday night wearing a deputy’s uniform and possibly carrying a gun, according to local reports.

Police have identified the deputy as Matthew Andrews, a two-year veteran of the sheriff’s department, NBC affiliate 9News reported. Andrews, who was arrested late Sunday, stands accused of helping Felix Dino Trujillo, 24, escape Denver County Jail at about 7 p.m. MT that evening, according to the station.

Trujillo remained at large Monday afternoon.

“Felix Trujillo may be armed and should be considered extremely dangerous,” the sheriff’s office said in a statement.

Trujillo had been jailed on charges of aggravated robbery and a parole violation, according to information obtained from the jail’s inmate database.

He was being held on $75,000 bond and was slated to appear in Denver District Court on May 13, according to court records.
