Hear 911 Call of Bizarre Robbery Attempt With Fake Explosives

For someone who had just learned one of his co-workers had a bomb strapped to his chest, the president and chief executive officer of Achieve Financial Credit Union in Connecticut sounded remarkably calm and matter-of-fact.

He called 911 and reported, "one of our VPs ... is the victim of a home invasion overnight. He states that he's strapped to a bomb. He's sitting in his car in the garage."

An audio recording of the Feb. 23 call was released today by police in Bristol, Connecticut. The victim, Matthew Yussman, lived in Bristol with his mother.

"The perpetrators also put a bomb under his mother's bed," the caller told authorities. "He's instructing me to vacate our New Britain branch because they're going to come and rob it."

Credit union vice president Matthew Yussman drove to the bank where police found him shivering in his car and wearing a vest that appeared to be a bomb.

Sources briefed on the case told ABC News the device was not real but, at the time, New Britain Mayor Erin Stewart called the episode "scary."

Police said at the time they were looking for two men "dressed in dark clothing wearing ski-masks and ski goggles" and driving an older-model white four-door Mazda.

There have been no arrests.
