DENVER (AP) — A Chicago man is accused of groping a pregnant woman and refusing to follow crew instructions on a JetBlue flight, prompting the plane to make an emergency landing in Denver.

The U.S. Attorney's Office in Denver said Tuesday that Marcus Covington has been charged with interfering with the duties of a flight crew and flight attendant.

Authorities allege the 32-year-old was intoxicated and groped the pregnant woman as he waited for the bathroom while on the Los Angeles-bound flight from New York late Sunday.
