OXFORD, ENGLAND, JULY 20 -- The driver of a bus that overturned and killed two Americans has been arrested, police said today.

All 59 others on the bus, which was carrying a group of U.S. teen-agers taking part in a special program at Oxford University, were injured in Thursday's accident. John Radcliffe Hospital in Oxford reported today that 16 people were still hospitalized.

Police identified the dead as students Lawrence Levine, 16, of Chappaqua, N.Y., and Autumn Dubose, 18, of Lilburn, Ga.

The driver of the double-decker bus, Gan Sharma, 40, was taken into custody Thursday night and charged with causing death by reckless driving, police said. They said alcohol was not a factor in the accident.

The driver, who was slightly injured, was released on bail today pending further investigation, said Chief Inspector Laurie Fray of the Thames Valley Police.

The bus was carrying gifted U.S. students taking a four-week summer school course at Oxford University's Magdalen College. The vehicle toppled as it turned off a highway near Wheatley, six miles east of Oxford, police said.

Fray said police intend to question Marilyn Whiteman, 39, who said Thursday the bus had passed her just before the crash at 80 to 85 mph. The British highway speed limit is 70 mph.

At Radcliffe Hospital, U.S. Ambassador Henry Catto spoke to the injured and to parents who flew here from the United States.

Brad Becker, 16, of Piedmont, Calif., said there was panic on the bus when it went out of control. "I said, 'Oh my God!' and people started screaming. . . . If it had fallen into the freeway, we'd all have plummeted into the path of cars. We'd have been killed," he said.
