According to prosecutors, Marcin Urbanski, 49, was taken into custody for committing felony theft, as the pilot had reportedly taken $9,000 from a Florida man in 2016 who had pledged to help him get a pilot's license and a job with Myanmar National Airlines.
"He was engaging in a cybercrime," Penobscot Assistant District Attorney Marianne Lynch said.
Lynch said police found out about the warrant for Urbanski's arrest because his name was included on a master list of people aboard the flight.
