The New York Port Authority, which owns the World Trade Center, is aware of terrorism occurring around the world and that the WTC is vulnerable to attack. It has therefore created the Terrorist Intelligence Unit within its police department, headed by Detective Sergeant Peter Caram, to gather information about terrorist groups and assess the vulnerability of its numerous facilities to attack. On this day, Caram writes a memo to the assistant superintendent of the Port Authority Police Department, reporting that the FBI has uncovered a terrorist threat: Two supporters of Ayatollah Khomeini are allegedly planning to bomb the WTC in the near future. Although the attack never occurs, this is the first of numerous occasions during the 1980s where the WTC is considered a potential target for a terrorist attack.
