A Scottish man is facing charges after the Philadelphia-to-London flight he was on made an unscheduled stop in Boston because he was allegedly being belligerent and disruptive.

A spokesman for Logan International Airport says John Alexander Murray of Glasgow was arrested shortly after US Airways Flight 728 landed at around 11 p.m. Monday. The plane departed for London two hours later.

Prosecutors say the 50-year-old Murray was blocking the aisle with his arm, which was in a splint. They say he would not move his arm, despite several requests from the crew, and demanded to be taken back to Philadelphia.

He is scheduled to be arraigned Tuesday in East Boston District Court on a charge of interfering with a flight crew.
