The FBI is trying to crack down on a man being called the “Route 91 bandit.”

Alleged to have robbed 11 banks in four New England states, the man now has a $10,000 reward on his head for info leading to his arrest, NBC News reports. 

All the banks the man has reportedly robbed are off Interstate 91—hence his nickname—and the FBI has claimed the robber is armed and dangerous after reportedly stealing from locations in Massachusetts, New Hampshire, Connecticut, and Vermont.

“In the interest of public safety, we’re asking anyone with information about this individual to contact us immediately,” Special Agent in Charge Joseph R. Bonavolonta of Boston said in a statement. “We need to put a stop to this man’s crime spree before someone gets hurt. He’s considered armed and dangerous so please take a close look at these images and reach out to us if you know who he is.”

The string of crimes started on Sept. 9, when the man—described as white and between 5’6” and 5’8”—robbed a bank in West Springfield, Massachusetts. He’s most recently alleged to have robbed a bank in Greenfield on Jan. 27. In one video, he’s seen wearing a hoodie reading Post University, a college in Waterbury, Connecticut.

For now, only one bank robber—the “Midday Bandit” of Chicago—on the FBI’s website is believed to have committed more robberies than the “Route 91 bandit,” per NBC.
