Suspected serial killer arrested

The lone suspect in the disappearance of a US teenager, Natalee Holloway, in Aruba in 2005 was paraded before reporters as Peruvians denounced him and detectives began interrogating him about the killing of a Lima student.

Joran van der Sloot arrived on Saturday at police headquarters. Wearing a bulletproof vest, his hands cuffed behind him, the 22-year-old stared straight ahead and did not respond to reporters' questions or make eye contact. His interrogation began almost immediately, General Cesar Guardia, chief of Peru's criminal police, said.

Mr Van der Sloot is suspected of killing 21-year-old Stephany Flores on 30 May in his hotel room in the Peruvian capital. Police in Chile arrested Mr Van der Sloot on Thursday. A Chilean police spokesman said the Dutchman told them he did not kill Ms Flores, who was found battered with a broken neck.

Police released video showing Mr Van der Sloot and his alleged victim entering his hotel room. Later video shows the Dutchman leaving the hotel alone with his bags.

"In two weeks we'll know if the girl had sexual relations or if there is alcohol in her blood," Dr Cesar Tejada, the deputy Lima medical examiner, said. He said toxicological reports should also be able to tell whether she was given a "date rape" drug.
