William Kennedy Smith surrendered on charges of rape and battery Saturday, and after being booked he called a police investigator's account "an outrageous lie."

Smith, the 30-year-old nephew of Sen. Edward Kennedy, was taken in handcuffs from the Palm Beach police station to the county jail before being released on $10,000 bail a few minutes later.He was accompanied by his mother, Jean Kennedy Smith; an attorney; and an old college friend, West Palm Beach lawyer Mark Mirkin.

Smith was charged Thursday with sexual battery, tantamount to rape, and with battery. A 29-year-old woman from Jupiter, Fla., told police she was raped March 30 after meeting Smith in a bar and driving him to his family estate.

After being freed, Smith, a fourth-year medical student at Georgetown University in Washington, discussed a nine-page police affidavit that detailed the charges.

"The version of events in that report is an outrageous lie," he said. "They represent an attack on me and on my family. I'm very much looking forward to a trial where the truth can come out."

Smith was fingerprinted, photographed and booked at the police station, then was taken by police in handcuffs to the Palm Beach County Jail, about a 15-minute drive away.

There, he posted $10,000 bond in a cashier's check and made a brief statement to reporters after leaving the building. He appeared composed but his hands were shaking.

He said he was advised not to comment further until after the trial. No trial date has been set, but arraignment was scheduled for June 14. Smith does not have to be present at the arraignment.

Smith ignored shouted questions as he and his mother walked to the car. Earlier, his mother said, "I'm distressed that someone is trying to ruin his life when he's trying to help people."

If convicted, Smith faces a maximum 41/2-year prison term under Florida sentencing guidelines.

"Willie's a tough guy and his mother's a tough lady," Mirkin said.
