(KSL News) -- A bomb scare tonight at Salt Lake's VA hospital turned into the real thing.
About 100 veterans were evacuated from this building--they're back inside tonight, after being forced outside when the bombs were discovered.
Police say they have a good idea who is responsible, but they're not saying who it is tonight.
A security officer saw the red duffel bag. He checked it out and discovered the two bombs.
The bag was found inside a building that provides housing for veterans released from the hospital, but not ready to go home yet.
Police call the bombs "improvised explosive devices" and say there were some sort of papers inside the bag with the bombs.
They won't say what information is on the papers-- and if the papers give any reason for why the bombs were left behind.
But when the bag was discovered, 100 residents and employees inside, most of them veterans were told to get out.
Ron, Evacuated Veteran: "They knocked on the door and asked us to leave because a suspicious package had been found."
Chief Bill Cowley, VA Hospital Police: "They were crudely manufactured, but it appears the intent was there.”
The Salt Lake bomb squad de-fused the bombs inside the hospital and took them away to a safer area to be detonated.
No patients in the hospital were affected, since the bombs were found in a separate building.
But because the VA hospital complex is a federal facility, the FBI is involved in the investigation and if caught, the suspect responsible could face serious federal bomb making charges.
