UPDATE (WKOW) -- Stoughton Police say not one, not two, but more than 20 bomb threats were phoned in to Stoughton Hospital within a 24 hour period.
Hospital officials say that prompted the entire building to be evacuated at around 1:00 p.m. Sunday afternoon.
16 patients were taken to a nearby nursing home and two others to Madison hospitals, as scheduled transfers.
Hospital officials say the first threats started coming in around 8:00 p.m. last night. Police checked it out and found nothing suspicious.
Then, Sunday morning, the calls started up again, this time hospital officials say with a different tone.
"Today (Sunday), the call had more details...they had us look in more obscure locations, and because of the time it would take to do that, with patient safety being our first priority at all times, we thought an evacuation was safer," said Kristi Hund, Vice President of Patient Services.
After deemed safe by local law enforcement, the patients were brought back to the hospital at around 3:30 p.m.
Police say more than one person is responsible for making the threats, but aren't commenting on any leads.
