The anonymous, typed letter stated that the bombs -- armed with remote detonators -- had been placed in areas where large crowds gather and that they would be detonated sometime between Wednesday and Friday.
DPS officials declined to disclose how or where the letter was found but said they did not think there was a danger to the University community.
The one-page letter stated that "the next three days will be by far the worst days in UNC's history" if Chancellor James Moeser does not stand on the steps of South Building and "fully endorse the war on Afghanistan ... and denounce homosexuality."
Glenn Grossman, co-chairman of the Carolina Alternative Meeting of Professional and Graduate Students, said he was upset by the letter but not surprised because the lesbian, gay, bisexual and transgender community faces violent threats at least once a semester. "My fear is superceded by my frustration that we don't have an infrastructure available to help with the unique burdens shouldered by the LGBT population on our campus."
The letter was written in a casual tone and hinted about possible locations of the bombs, listing campus map coordinates.
After the letter was found, a team of 17 officers conducted searches around campus, said Police Chief Derek Poarch. "Our searches resulted in nothing being found that would be in any way a threat to students, faculty or staff," he said.
Poarch said police will keep looking into leads but have no suspects at this time.
Poarch said the University usually receives one or two bomb threats each year, often near the time of break or midterms, although most threats come via phone rather than letter. "We take any and all threats seriously whether they are specific or not," he said.
In August, a pipe bomb was found on Cameron Avenue by Davie Hall. The bomb was detonated by State Bureau of Investigations officials. The incident caused no injuries, but Cameron Avenue was shut down for almost four hours.
