Brothers Re-Arrested in Holloway Case

Two brothers previously detained in the disappearance of missing student Natalee Holloway and one other man have been arrested in the case, ABC News has learned.

Deepak Kalpoe, a 21-year-old Suriname national, his 18-year-old brother, Satish, and another man whose name has not been released have been arrested by Aruban authorities and are being turned over to Dutch investigators for questioning, Dave Holloway, Natalee's father, told ABC News. He said an FBI official close to the investigation called him and informed him of the arrests today. The Kalpoe brothers have been arrested and the third person of interest will be questioned. They have not been charged.

The Kalpoes and 18-year-old Joran van der Sloot were the last people seen with Natalee as the four left a nightclub on May 30 — the night the 18-year-old Alabama student disappeared at the end of a high school graduation trip to the Dutch Caribbean island.

The young men were arrested on June 9, but the Kalpoe brothers were later released after a judge ruled there was not enough evidence to hold them. Van der Sloot is the only person in custody in the case, and no one has been charged.

Van Der Sloot Scheduled for September Release

Van der Sloot is scheduled to be released from custody Sept. 4. Dave Holloway said the arrests of the Kalpoes give him hope that authortities will keep van der Sloot in custody.

"The re-arrests give me hope that Dutch authorities will get to the bottom of this," he said. "The first interrogators were able to get this far but I'm confident that they also keep Joran van der Sloot in custody after Sept. 4."

The re-arrests come weeks after Deepak Kalpoe filed a complaint with police against Beth Holloway Twitty and asked that she stay away from him. Holloway Twitty has repeatedly said she believes the three young men were involved in Natalee's disappearance. They have denied the allegations.
