Naomi Campbell was freed on bail Friday following her arrest the day before at London's Heathrow Airport.

The supermodel had just boarded a British Airways flight headed to Los Angeles when she was told that one of her two checked bags at the new Terminal 5 had gone missing. According to witnesses, Campbell had a fit and allegedly spat on a cop that was called to the scene.      

She was escorted off the plane and arrested on suspicion of assaulting a police officer. The runway diva was released shortly after midnight on Friday and told to return in late May.      

"So far as we are aware, BA has still failed to offer any explanation as to why her bag went missing at Terminal 5," said Campbell's rep.

BA has been beset by problems with the high-tech check-in and baggage handling systems at the 4.3 billion pound terminal, reports Reuters. Hundreds of flights have been cancelled and tens of thousands of bags have gone missing, costing the airline about 16 million pounds since the terminal's opening last month.
