Authorities have arrested a man believed to be responsible for several bank robberies in the Tucson area over the last few months, officials said May 20.

Ronald Joseph Wilger, 47, was taken into custody by Tucson police detectives and the U.S. Marshals, after he was found at a motel on East Benson Highway, according to Tucson Police Department news release.

Tucson police have been working with the Pima County Sheriff's Department over the past several weeks to identify Wilger, who is a suspect in at least seven bank robberies. On each occasion, he claimed to have a gun, and during the last incident, he threatened an employee with violence, police said.

Wilger was booked into the PIma County jail Friday on a felony parole violation warrant, along with the armed robbery warrant.
