An Aruban prosecutor on Tuesday ordered a 19-year-old man arrested on suspicion of involvement in Natalee Holloway's disappearance held in detention for eight more days.

Prosecutors, who have only identified the suspect as having the initials G.V.C., said he "was arrested in the ongoing investigation into the disappearance of Miss Holloway in May 2005."

"G.V.C. is suspected of criminal offenses that may be related to the disappearance of Miss Holloway and of offenses related to dealing in illegal narcotics," prosecutors said in a written statement released Tuesday.

The suspect, who was identified in the media as Geoffrey van Cromvoirt, was arrested Saturday but the prosecutor's office had not previously disclosed why the man was held.

The case of the suspect was set Tuesday to go before a judge who would determine if the arrest and detention were justified.

Holloway, then 18, of Mountain Brook, Ala., was last seen leaving a bar with Dutch teen Joran van der Sloot and two Surinamese brothers on May 30 — the final night of her high school graduation trip to the Dutch Caribbean island. The three local men were jailed but later released after a judge ruled there was not enough evidence to hold them.

Joe Tacopina, a lawyer for van der Sloot, called the latest news "a good development" for his client as the two do not know each other.

"Obviously, we want this to be resolved but also I want my client to be cleared and given
that there's no relationship between Joran and van Cromvoirt, that's a good fact," Tacopina said in an interview on FOX News Tuesday.

Tacopina said the new arrest stemmed from "forensic information" from a shirt found during the investigation.
