Indonesia's human rights commission is calling for an inquiry into the death of a suspected terrorist while he was being held by the country's Special Forces counterterrorism squad.

Siyono -- held on suspicion of involvement with Jemaah Islamiyah arms factories -- was arrested March 8, but died after a reported scuffle with Detachment 88 members a day later.

The National Commission on Human Rights stated Sunday that it will investigate the case, urging a transparent inquiry.

Commission manager Nasution -- many Indonesian's use just one name -- underlined that although acts of terrorism were not justifiable, the arrest and interrogation process may have violated the 34-year-old's human rights.

Siyono was arrested March 8 at a mosque near his home in Klaten, Central Java, while worshiping.

On March 9, police searched his home and began to interrogate him.

Later that day he was announced dead.

On Sunday, police spokesperson Brigadier General Agus Rianto denied that Siyono had died during interrogation, saying that he instead died in hospital after a fight with a member of the counterterrorism squad.

"He was killed, probably in a collision and struggle during a fight with a member [of Detachment 88] because he attacked the officer as he was being taken back [to the police station]," Rianto was quoted as saying by beritasatu.com.

He said that once the situation was under control, Detachment 88 personnel took him to a nearby hospital for a checkup.

"His life could not be helped and he died in hospital," said Rianto, adding that Siyono's body had been handed over to his family for burial.

A source in Detachment 88 who declined to reveal his identity told beritasatu.com that an autopsy had not been carried out on the body.

On Sunday, the Commission stated the inquiry should be used to evaluate Detachment 88's performance as the National Counterterrorism Agency (BNPT) will soon receive additional government funding of up to 1.9 trillion rupiah.

It warned the House of Representatives to be more careful when considering revisions to the country's anti-terrorism law proposed on the back of the Jan. 14 Jakarta terror attack in which eight people died.

The new anti-terror law is expected to strengthen Detachment 88's authority in the process of arrest, detention, and de-radicalization.

The Jemaah Islamiyah is an affiliate of al-Qaeda in Southeast Asia blamed for the 2002 Bali bombings in which 202 people died.
