Cabin crew on an Alitalia flight overpowered a 48-year-old man who attempted to hijack the plane, according to Herald Sun.
Valeriy Tolmashev, from Kazakhstan, held a nail file to an air hostess' neck demanding the plane be diverted to Tripoli, Libya, USA Today said.
All 131 passengers aboard the flight were safe upon arrival into Rome on Sunday evening, Alitalia said in USA Today.
Tolmashev's motives are not known, according to Italian investigators. He had no known links with international terrorism, Herald Sun said, and a lack of a police record.
