(CNN) -- All five of the Delaware County Community College campuses in Pennsylvania remain closed on Monday, four days after an e-mail threatening unspecified violence was received by college faculty, college officials said.
West Whiteland Township Police Chief Ralph Burton tells CNN the e-mail was sent to four to six faculty members at the Exton campus in West Whiteland Township on Thursday.
All campuses were immediately closed.
Police do not have any specific details on a suspect, Burton said. West Whiteland Township Police along with neighboring police departments and the FBI have interviewed over 160 faculty members to try to establish any possible leads, he said.
The e-mail, just one paragraph long, threatened violence on Monday or Tuesday at the college's Exton and Downingtown campuses, both located in Chester County. The writer of the e-mail mentions feeling stressed out and unhappy, Burton said.
Authorities do not know why the e-mail was sent to specific faculty members.
Police are taking this threat seriously, but are paying extra attention to it in light of the recent massacre at Virginia Tech, Burton said.
Chester County's District Attorney Joseph Carroll told CNN there is the "possibility that this could be another devastating incident."
The Exton campus serves approximately 10,000 day students and has no dormitories. Students were notified of the threat via e-mail, signs posted on campus and a message on the school Web site.
The e-mail came from a hotmail.com account and authorities have been in contact with Microsoft, which owns Hotmail, to try to establish an identity on the suspect.
Delaware County Community College will remain closed indefinitely at the discretion of the college president.
Burton is meeting Monday with college officials, and the district attorney for an update on the investigation.
