A Scottish man who was branded unruly and disruptive by the flight crew on a Philadelphia-to-London jet that was diverted to Boston has been ordered held on $300 bail.

Prosecutors say Glasgow resident John Alexander Murray's arm was in a splint and he refused the crew's requests to keep it out of the aisle. They say he then became belligerent and demanded to be taken back to Philadelphia.

A spokesman for Boston's Logan International Airport says Murray was arrested after US Airways Flight 728 landed at around 11 p.m. Monday. The plane departed for London two hours later without him.

Murray pleaded not guilty to a charge of interfering with a flight crew at his arraignment Tuesday at East Boston District Court. The 50-year-old was ordered to return to court Dec. 1.
