A man was taken into custody shortly after 10 p.m. Friday night after an hours long standoff inside a Benbrook hotel, according to FBI spokeswoman Melinda Urbina.
The man is suspected in several bank robberies in Irving, Southlake and Fort Worth, Urbina said.
The FBI investigation led officers to a Days Inn off of Southwest Loop 820 near Las Vegas Trail where officers believed the suspect to be. Once they arrived, the suspect barricaded himself inside a room and held police at bay for several hours, according to police.
When police entered the room the man had to be treated on-site for an apparent drug overdose, but was later pronounced dead by the Tarrant County Medical Examer, according to the FBI.
The man was alone in the room, so there were never any hostages involved and no shots were fired at police.
The FBI has not released the name of the suspect.
Fort Worth Police and Benbrook Police assisted in the investigation.
