A Delta flight from Boston to Newark returned to Logan International Airport Sunday afternoon after police received a report that a passenger had made threats about the flight, according to Massachusetts State Police.

The unidentified male passenger ended up being escorted by troopers off of Delta Airlines Flight 5770 at Logan International Airport.

The passenger’s two carry-on bags were searched by members of the Mass State Police Bomb Squad and explosive ordinance detection dogs. They did not find any weapons, and the passenger did not have any checked luggage.

After the passenger was escorted off and his bags were cleared, the airplane departed again for Newark.

“Delta Airlines Flight 5770, Boston to Newark, returned to Logan Airport this afternoon after an anonymous third part caller reported to a New Jersey police agency that a passenger aboard the plane had allegedly made threats related to the safety of the flight,” a State Police spokesperson said in a statement.

The passenger has not been charged. The investigation is ongoing.
