UPDATED 6:47 P.M.: Police Seek Escaped Inmate, 'Considered Dangerous,' From Black Hawk County Jail

Updated 6:47 p.m.:

A man escaped from the Black Hawk County Jail earlier today and is considered dangerous, Sheriff Tony Thompson said today.

Authorities are seeking Jeremy Mask, 25, a white male, 6 feet tall, 190 pounds (see photo). They are also looking for a car he allegedly stole after escaping. The car is a light blue 1998 Mercury Grand Marquis with Iowa license plate Z 0010. 

Officials are asking the public to immediately call 911 if they see Mask or this vehicle.

KWWL reported Thompson says Mask may also have robbed a business in Toledo after escaping. Thompson told reporters Mask escpaded from the jail just before 3 p.m.

KWWL reported:

Mask was able to escape through a fire tower in the jail... Sheriff Thompson says it's no excuse, but he believes two separate contractors working in the jail at the time contributed to the security breech. The two contractors are upgrading security systems in the jail, including video cameras in the jail and the jail visitation telephones.

Mask has had a series of run-ins with the law for drugs, robbery and burglary, and has also previously escaped a drug treatment facility.

Mask escaped the facility in April and then was arrested in connection with a robbery at a local drug store, and in 2010 had a prescription drug arrest and also a burglary conviction for breaking into a home and stealing prescription drugs, according to the Waterloo-Cedar Falls Courier.
