(CBS) — A bank robber dubbed the “Hooded Bandit” has struck for the sixth time, holding up a northwest suburban bank on Monday.

WBBM Newsradio’s Bernie Tafoya reports the suspect – a middle-aged white man – wore hoodies during all six bank robberies, according to the FBI. He hit a Chase branch in Bensenville at 4:30 p.m. Monday.

“He walked in and presented a note to the teller. He demanded money, he received money, and fled on foot,” said FBI spokeswoman Joan Hyde.

The Hooded Bandit used a gun in his first heist, but hasn’t shown one since.

“The witnesses had described him as a 50- to 60-year-old white male, about 5’8” to 6 feet tall. While his head is covered with those hoodies, they have described him as having gray facial hair,” Hyde said.

Photos of the suspect were posted on the Bandit Tracker Chicago website.

The suspect first started robbing banks a year ago.

“This is the first time that we believe he has struck in 2014. His other robberies all occurred in 2013, from April continuing all the way through to December 9th,” FBI spokeswoman Joan Hyde said.

That means he didn’t strike at all during Chicago’s brutal winter, begging the question whether he left the town for a while.

“If we catch him, we can ask him those questions,” Hyde said.
