HONOLULU (HawaiiNewsNow) - Authorities are looking for a dangerous bank robber they've dubbed the "Backpack Bandit."
He's struck four Oahu banks this year.
He always has a backpack, glasses and hat, but more importantly he's carrying a gun and goes to multiple tellers demanding cash.
He also keeps his finger on the trigger, which makes officers worry he could be one twitch away from tragedy.
The FBI has stepped up and is offering a $10,000 reward for anyone who turns him in.
"We are also hoping that someone out there likes the idea of getting $10,000 for Christmas more than they like being friends with the Backpack Bandit," FBI special agent Tom Simon said.
"The suspect in this case appears to be escalating his level of violence and we're concerned in the future someone may get hurt," HPD Maj. Richard Robinson said.
The man is Asian or Pacific Islander, in his 30's. He's between 5'4" and 5'6" tall and weighs 180 to 200 pounds.
He has worn a wig in two of the robberies.
