ORANJESTAD, Aruba – Police have arrested two Surinamese brothers who had been previously detained and released in the disappearance of Natalee Holloway, a government official said Friday.

Satish and Deepak Kalpoe were arrested along with a third person, according to government spokesman Ruben Trapenberg.

Trapenberg said he did not know if the arrests were connected to the Holloway case and no other details were immediately available.

David Kock, a lawyer for Satish Kalpoe, said he was not aware of the arrest.

Satish Kalpoe, 18, and his 21-year-old brother, Deepak, were released from jail in July after a judge ruled there was not enough evidence to hold them in Holloway’s disappearance.

The 18-year-old Holloway, from Mountain Brook, Ala., was last seen on May 30, the final night of a high school graduation trip to the Dutch Caribbean island.

The brothers had been arrested June 9 along with Joran van der Sloot, 18, who authorities have identified as a suspect in the case though no charges have been filed.

A judge is scheduled to hold a hearing in September to determine if there is enough evidence to continue holding van der Sloot.

Holloway was last seen leaving a bar with the Kalpoe brothers and van der Sloot in the early hours of May 30. Extensive searches of the island have produced no sign of her.
