Boston ? Howie Day was arrested at Logan International Airport for rowdy behavior on a Boston-bound flight after he became intoxicated from a mix of alcohol and a sleeping pill.

The 24-year-old pop singer pleaded innocent to a charge of interfering with a flight crew at his arraignment Friday in East Boston District Court. He was released on personal recognizance and refused to comment to reporters afterward. He’s due back in court March 16.

Authorities said the charge carries a fine of $10 to $500, a jail term of one month to six months, or both.

Day, who is from Brewer, Maine, was returning home for the holidays and took a pill to help him sleep on the flight from Dallas, said his attorney, Paul Kelley.

“He had a couple of drinks. The pill interacted with the drinks and he became intoxicated. He feels badly if he inconvenienced anyone or caused any discomfort,” Kelley told reporters outside court. “He has and will apologize, and our hope is that we’ll be able to resolve this thing as promptly as possible.”
