Federal officials say a JetBlue flight out of Boston had to be diverted when a fight broke out between brothers.

The plane en route to Fort Lauderdale, Fla., landed in Raleigh, N.C., where it was grounded for two hours Saturday evening after a scuffle that started with someone smoking in the bathroom. One passenger was arrested, CNN reported.

The fight was between two brothers after one had smoked in the airplane restroom, witnesses told CNN.

But a spokeswoman for the federal Transportation Security Administration said three people were involved in the fight and one person suffered a facial injury from a possible punch.
