GLENDORA — A serial bank robber dubbed the “Puffy Coat Bandit” robbed a bank of an undisclosed amount Friday, authorities said.

The robber entered the Union Bank in the 600 block of West Route 66 at about 4:30 p.m.

Glendora police Lt. Jamie Caldwell said the suspect presented a note demanding money to one of the tellers. He also simulated having a weapon during the heist.

The suspect took the cash and left.

The robber was believed to be a serial bandit the FBI is calling the “Puffy Coat Bandit” due to the ski jacket-type outerwear he’s sported during several area heists in recent weeks, FBI spokeswoman Laura Eimiller said.

The bandit has been linked to three other bank robberies since Dec. 20, FBI officials said in a written statement. They include: A Dec. 28 robbery at Mission Oaks Bank in Lake Elsinore; a Dec. 22 heist at Premier Services Bank in Corona; and Dec. 20 at U.S. Bank in Chino.

Officials described the Puffy Coat Bandit as a white man in his late-30s to mid-40s, of thin to medium build and standing 6 feet 1 inch to 6 feet 4 inches tall. He’s been seen wearing a black ski-type jacket and a black beanie.

A light colored sedan, possibly a Ford or Mercury, has been witnessed in connection with the crimes, according to the FBI. In the Glendora case, the car was described as brown or maroon.

He’s considered armed and dangerous, and anyone who sees him is advised to call the FBI’s 24-hour tip line at 310-477-6565, or 911.
