Glavas's detention was extended on grounds of the gravity of the crimes he is suspected of, but not on grounds of possible witness-tampering, which was why he was initially taken into custody on October 26.
"Investigating judge Zdenko Posavec partially accepted the motion by the State Prosecutor's Office and extended the detention of Branimir Glavas only on grounds of the gravity of crimes. The judge believes that the circumstances which existed at the time of the first ruling on detention have not changed and that the role of Glavas in the crimes was such that it justifies his detention on those grounds," the Zagreb County Court said on its web site.
In the ruling which prolonged Glavas's detention until December 26, Judge Posavec said that there was no longer any danger of witness-tampering because only defence witnesses remained to be questioned.
Glavas's attorney Ante Madunic said that he would appeal the ruling and file a constitutional complaint.
Earlier in the day the attorney said that his client had no intention of breaking off his hunger strike unless he was released from custody and that there was little chance that Glavas would survive if he remained in custody.
Madunic also repeated that Glavas was not trying to kill himself, but was on a hunger strike primarily because of the Sellotape case, which he said was based on the testimony of only one co-accused.
Despite unfavourable forecasts, the attorney said that the condition of his client, who has been on a hunger strike for 29 days, was good.
"He speaks with slight difficulty because his throat is sore, obviously due to lack of vitamins, but he is still in good shape and mentally and physically fit to follow the proceedings," Madunic said.
Zagreb County Court spokesman Kresimir Devcic confirmed Madunic's statement, adding that Glavas was still refusing medical examination and weighing.
In the investigation conducted by the Zagreb County Court Glavas is accused of personally ordering the ill-treatment and murder of Serb civilians Cedomir Vuckovic and Djordje Petkovic and the torture of another three Serb civilians.
The Osijek County Court launched an investigation into Glavas in another case, called the Sellotape case, in which he is suspected of ordering the abduction and killing of civilians on the Drava River bank in Osijek in 1991.
