Two men face charges after separate incidents of unruly behavior on flights

A man accused of rubbing a fellow passenger's breast and another who allegedly assaulted a flight attendant while on flights face criminal charges, the Department of Justice announced. The grand jury indictments come after federal officials said they would step up enforcement against bad behavior in the skies.

Ivan Lopez, Jr., 26, was on United Airlines flight from Las Vegas to Dulles International Airport, outside Washington, D.C., on Christmas Eve when he allegedly rubbed the breast of the passenger sitting next to him, who was asleep, according to court documents. The passenger woke to find his hand on her breast, the documents state, and yelled "get away from me!" at Lopez. 

A flight attendant told investigators Lopez admitted to her he had assaulted the passenger, according to the documents, but Lopez told investigators he went to get the woman's attention by poking her in the shoulder so he could ask what she was listening to on her headphones, but missed her shoulder and accidentally poked her breast when there was turbulence.
