DENVER (KKCO) -- Halloween is still months away, but one group is already playing a dangerous game of trick or treat.
The Denver and Aurora Police Departments and the FBI's Rocky Mountain Safe Streets are searching for a group they've dubbed "The Trick or Treat Bandits," who may be responsible for nine bank robberies in the Denver area.
FBI Media Coordinator Dave Joly says the suspects are all described as black males in their early to mid 20s, between 5'6" and 6'0" in height, weighing between 160 and 200 pounds.
Photos from the scenes show the men carrying what appear to be handguns, and one is pictured with a pillowcase, which could be used as a trick-or-treat goodie bag of sorts.
According to witnesses, the men walk into the banks, demand money while threatening people with their weapon and then flee.
Jolly says they are considered armed and dangerous, so if you see them, do not approach them. Call law enforcement immediately at 303-629-7171. You can also remain anonymous and earn up to $2,000 by calling Crime Stoppers at 720-913-STOP (7867).
If caught and convicted, the men can face 20 years in prison for each offense, and the punishment increases if a dangerous weapon is used.
