The FBI is offering a reward of up to $10,000 for information leading to the arrest and conviction of a serial bank robber dubbed the "Barrel Chested Bandit."

The unknown suspect is believed to have robbed eight banks in Arizona, New Mexico, and Texas from August 2016 to February 2017.

The first robbery occurred in Tucson, Arizona on Aug. 24, since then the suspect has held up four different banks in Texas and three in New Mexico.

In each of the robberies, the man produced a small semi-automatic handgun, verbally demanded money from the teller, obtained an undisclosed amount of cash, and exited the bank on foot, according to the FBI press release.

The suspect is described as a large white male in his mid 40s to early 50s. He is between 5'6" and 5'10" weighing approximately 250 pounds.

The FBI says he has worn a ball cap, sunglasses, and blue jeans in every robbery. He has also worn a long- or short-sleeved t-shirt and athletic shoes. In one robbery, he wore a black or gray ski jacket. He has also worn a white mustache or goatee in several robberies.

The "Barrel Chested Bandit" should be considered armed and dangerous.
