Reports said Rigi was captured on a flight from Dubai to Kyrgyzstan.

Iranian Interior Minister Mostafa Mohammad-Najjar told reporters that Rigi was consequently transferred to Iran.

An Iranian Prosecutor told Fars news agency that the notorious terrorist was arrested early Tuesday in a pre-planned operation.

"Rigi's arrest was eventually made through a series of security measures taken for a long period of time. He is now in Iran and will be handed to security and judicial officials," he said.

The Jundallah group has claimed responsibility for numerous terrorist attacks in Iran. The group has carried out mass murder, armed robbery, kidnapping, acts of sabotage and bombings. They have targeted civilians and government officials, as well as all ranks of Iran's military.

The Pakistan-based terrorist organization denies having any link to Washington but Rigi's brother, arrested earlier and now in Iran's custody, confirmed in an interview with Press TV that the Jundallah leader had, in fact, established links with the US administration.

Abdolhamid revealed that a go-between, named Amanollh-Khan Rigi, put the terrorist group in connect with the US administration, which had promised the anti-Iran terrorist group a safe haven in Pakistan.

"His name is Amanollah-Khan Rigi. He is my father's cousin. He was a royalist during the Shah's regime," Abdulhamid told Press TV.

"After the [1979] Revolution in Iran, he left the country via Pakistan and sought asylum in the United States."

Abdulhamid said the Americans had asked Amanollah-Khan to forge a link between the US and Jundallah. "The Americans asked him [Amanollah-Khan] to introduce them to [Abdolmalek] Rigi in Pakistan and that's how link was established."

He also claimed to have visited the US Embassy in Pakistan to seek more US cooperation with the terrorist group.

According to Abdolhamid, the Pakistani government was well aware of the whereabouts of the Jundallah terror group.

"It is impossible to believe that Pakistan is unaware of Jundallah's presence on its soil," he said. "Pakistan is a perfect haven for Jundallah."
