An El Al flight from Prague to Tel Aviv was forced to make an emergency landing in Greece after a “violent passenger” attempted to enter the plane’s cockpit, according to Israeli media reports on Thursday.

The Israeli national airline wrote in a statement that flight LY2522, scheduled to fly from the Czech capital to Israel, made an emergency landing in Thessaloniki, Greece where the disruptive passenger was apprehended by local security services.

"El Al has a zero-tolerance policy for violence, and we shall continue to ensure the safety of our passengers,” the statement said.

Israeli news outlet N12 later reported that the passenger was detained by on-board security personnel after he attempted to infiltrate the cockpit. According to N12, onboard security officers described the passenger in question as being “apparently of Arab descent.”

According to El Al’s statement, the circumstances of the incident are being investigated.
