MIDDLESEX COUNTY - A World War I-era Cooper bomb was unearthed Sunday afternoon at the campus of Middlesex County College.

The Navy was called to the college along with the bomb squad to remove the explosive.

The section of the campus where the bomb was located was at one time the site of the former Raritan Arsenal.

The Army Corps of Engineers has been working to clean out the site of any buried weapons left behind.

"They could not make an actual determination if it was live or not, but they determined that it was stable enough to transport back to Naval Station Earle," said Chief Neil Brosnian, of the Middlesex County College Police.

Police say the bomb was severely disintegrated, but was still 12 to 14 inches in length.

Cooper bombs are aerial bombs dropped from planes onto targets during war.
