SOLO/JAKARTA - Indonesian police removed a radical Muslim cleric suspected of leading the Jemaah Islamiah militant network from his hospital bed in central Java on Monday as his weeping supporters and security forces clashed outside.

Abu Bakar Bashir, 64, was flown to Jakarta and taken to a police hospital, but there was no immediate word on when he would be questioned about a series of Christian church bombings and an alleged plot to kill President Megawati Sukarnoputri.

Supporters tried to prevent police removing Bashir, who denies any involvement in terrorism, from the hospital in the city of Solo as international pressure mounts on Megawati to act against Muslim extremists following the bloody Bali bombs.

Witnesses said plainclothes police broke down the door of Bashir's hospital room after three supporters locked it and lay on top of their leader as fellow students fought police outside.

The policemen kicked and hauled them off Bashir, put the cleric in a wheelchair, pushed him from the hospital and drove him away, they said.

Outside, hundreds of teenagers, tears streaming down their faces, threw rocks and exchanged punches with police. Ten policemen were seen bleeding.

After police drove away with Bashir, who has not been accused of involvement in the Bali blasts which killed more than 180 people although Jemaah Islamiah is suspected of being behind them, an aide called for calm and most of his supporters left.

"He has been taken, but everyone must calm down and show we are good Muslims," said Irfan Awwas. "This was an abduction of an preacher amid his own supporters. This was inhumane."

TEST FOR MEGAWATI

Chief Security Minister Susilo Bambang Yudhoyono also sought to cool the mood over Bashir's detention, which some foreign governments have said could foment demonstrations in which Westerners might become targets.

"We should not become emotional," Yudhoyono told a Jakarta news conference. "Abu Bakar Bashir is summoned by the police for investigation, not for punishment. He will not be declared guilty or convicted before a court decides that."

Mahendradatta, one of Bashir's many lawyers, fumed, however. "This was state terrorism," he told reporters in Jakarta.

Another lawyer, Muhammad Assegaf, said Bashir had refused to sign documents acknowledging his detention. Assegaf, a prominent lawyer who has long represented the family of former President Suharto, quoted police as saying the hospital in Solo had pronounced Bashir healthy but said he needed four days' rest.

Foreign diplomats see the investigation of Bashir, taken to hospital with what doctors said were heart and respiratory ailments, as a litmus test of Megawati's resolve to crack down on Muslim extremists after the Bali bombings.

The world's most populous Muslim country has long taken a soft approach to radical Islamic groups, partly to avoid a backlash from moderates who might perceive any crackdown as a response to foreign pressure.

But world leaders have urged Jakarta to move more decisively in the fight against militants following the Bali blasts, which killed mostly foreign tourists, about half of them Australians.

Suspicion swiftly settled on Jemaah Islamiah.

Although investigators say they have not established a link to Jemaah Islamiah, a police spokesman said they would soon release sketches of three men of Indonesian appearance and suggested they were now suspects.

"In one or two days, the investigation team will publicize the sketches of the people suspected of being the perpetrators," Brigadier General Edward Aritonang told reporters on Bali.

When police announced last week they had the sketches and that a hunt had been launched for them across Indonesia, a huge archipelago of 17,000 islands and 210 million people, the men were described only as possible suspects.

BID LADEN ADMIRER

Bashir, 64, insists Jemaah Islamiah does not exist, although he is an open admirer of Osama bin Laden, the Saudi-born leader of al Qaeda blamed for the September 11, 2001 attacks on the United States.

Jemaah Islamiah, which Washington has linked with al Qaeda, has been accused of plotting bomb attacks on Western targets as part of a jihad, or holy war, intended to establish an independent Islamic state across the region.

Bashir was rushed to the Solo hospital six days after the Bali blasts and was placed under detention there, but police said they were not allowed by law to question him while he was ill.

On Sunday he said he was feeling better.

He was formally detained after investigators returned from questioning Omar al-Faruq, a self-confessed al Qaeda operative arrested in Indonesia in June and turned over to Washington.

Bashir has said he believes the United States was behind the Bali attacks, which he has condemned as a "brutal act."

Bashir has been at odds with Indonesian authorities before.

He was jailed in 1979 under former autocrat Suharto for agitating for an Islamic state. In 1985, he fled to Malaysia, returning only in 1999 after Suharto, who kept a tight lid on militant and political Islam, had lost power and his subversion laws were repealed.
