The FBI said in a statement that the alleged mugger is about six-feet-tall, slender and aged in his 30s.

Surveillance images from the robberies show the man wearing a hooded sweatshirt, a cap and sunglasses.

The four robberies occurred on Wednesday at a Northglenn TCF bank, Thursday at a Chase Bank in Westminster, Sunday at the Broomfield TCF Bank and Monday at a Chase Bank in Thornton.

The FBI would not disclose how much money was taken or when the demand letters would be released.

'Those letters are evidence in the investigation. We are not able to release them just yet,' FBI spokesman Dave Joly said in an email to MailOnline.
