A message for would-be bank robbers:

If you rob a bank, not only will you have the FBI on your trail. You might also get a ridiculous picture of you in a cowboy hat circulated to thousands of people, and be dubbed the "Brokeback Bandit."

Tuesday morning, the Brokeback Bandit went to the City Center U.S. Bank branch in the 1400 block of Fifth Avenue. The man – believed to be 6-foot-2, in his 30s with an athletic build – approached a teller and demanded money.

No weapon was seen or implied, an FBI spokeswoman said. But he did have a signature cowboy hat.

The FBI did not say how much money was taken in the robbery.

Anyone with information is asked to call the FBI's Seattle office at 206-622-0460.

"Brokeback Mountain," was an award-winning 2005 film that detailed the romantic relationship between two cowboys. Starring Heath Ledger and Jake Gyllenhaal, it was adapted by the short story of the same name by Annie Proulx.

"We don't know his sexual orientation," FBI spokeswoman Robbie Burroughs said. "The name was because of his cowboy hat."

The FBI acknowledges some people may complain about the nickname, but say the name is not ill-intentioned.

"The guy's got a cowboy hat. It's a popular movie," Burroughs said. "Let's not be too overly concerned about the bank robber's feelings."
