Aruba ? A 19-year-old man arrested in the disappearance of a young Alabama woman was released from jail on Monday, but prosecutors said he remained a suspect.

In a statement, the prosecutor’s office also said Monday that a 20-year-old man with the initials A.B. was arrested in the disappearance of Natalee Holloway on Saturday and was released after six hours of interrogation. No details were provided.

Geoffrey van Cromvoirt, the 19-year-old who was arrested on April 15, is suspected of “criminal offenses that may be related to the disappearance” of Holloway, prosecutors said.

“He has been released because the grounds for his detention are no longer there. He remains a suspect,” the prosecutor’s office said without elaborating.

Holloway, of Mountain Brook, Ala., was 18 when she vanished on May 30 – the final night of a high school graduation trip to this Dutch Caribbean island.

Authorities have previously arrested seven people in connection with Holloway’s disappearance and then released them for lack of evidence.
