A man attempted to rob a Salt Lake credit union using a pipe bomb early Saturday afternoon.

At 1:53 p.m., the suspect walked up to the drive-through window at the Deseret First Credit Union, 147 N. 200 West, and began hitting the teller buzzer repeatedly, according to Salt Lake Police Lt. Sandra Urry.The teller told the man the credit union was closed and he would have to come back later. After continuing to ring the buzzer, the suspect sent what the teller believed was pipe bomb through the vacuum tube. The teller then called police, as the suspect fled on foot without receiving any money from the teller, Urry said.

"The object had all the components of a bomb," Urry said. "The teller did the right thing by not opening the tube to see if it was actually a bomb."

Bomb detectives were called out to the scene and rendered the object safe by exploding it on site, Urry said. Investigators are looking to see if the device was an actual bomb.
