MAUI (HawaiiNewsNow) - A man who tired to rob the First Hawaiian Bank in Kahului at about 11:30 a.m. Wednesday, threatened to blow up the bank before running away empty-handed.
According to police, the suspect handed a teller a note demanding that money be placed into a bag.
The man fled without any cash, but left a suspicious device on the counter and said he would be "blowing the place up," police said.
Police say it was actually a brown tube and a nine volt battery wrapped with wires and covered in cellophane.
It had about the same explosive potential as a model rocket ignition.
The police bomb squad rendered it safe.
The robber is described as a white male, approximately 6 feet tall, with a slim build, wearing a camouflage jacket and camouflage pants.
Maui police are being assisted by the FBI and ATF in this investigation.
