Doctor pulled from cruise over fake bioterrorist message

A Nashville neurosurgeon was taken off of a Carnival cruise after an imposter account on Twitter posted a message that the doctor was planning to commit a bioterrorist attack.

Jack Kruse was planning to speak to the passengers of a Carnival Magic cruise on Monday as part of the 5th Annual Low-Carb Cruise. The ship was to launch on Sunday from a Galveston, Texas, port. Kruse was escorted off the cruise after the suspicious tweet was detected, the Houston Chronicle reports.

"Security confiscated dynamite," the fake Twitter account said, according to the Houston Chronicle. "Talk won't be as explosive as one at PaleoFx. Still have vial of Legionnaires for epic biohack. #lccruise12."

In addition to the tweet, the cruise line received a call alleging that the doctor planned to engage in a viral biohack on the ship. The U.S. Coast Guard, the Galveston police, the Department of Homeland Security and the FBI were all informed about the tweet.

"It was like being in a movie, and it was surreal," Kruse said, according to the Houston Chronicle. "Having the room completely trashed, and I was asked all of these crazy questions. I had no idea what they were talking about."

Officials cleared the doctor before the ship left the port, but the captain would not permit Kruse to re-board.

"Since the safety and well-being of my guests and crew is my number one priority, every security threat is taken seriously and fully investigated," Captain Giovanni Cutugno said, according to the Houston Chronicle. "It is for this reason that I felt it was in the best interest of all my guests to err on the side of caution and not allow him to set sail as planned."

The investigation is ongoing into the identity of the person who created the account and posted the tweet.
