JAKARTA, June 4 (Xinhua) -- The Indonesian Police Wednesday called on the government to outlaw the radical Islam Defender Front (FPI) whose dozens of members were detained for Sunday's attack on a religious freedom rally.

    "We remind authorities that the FPI has thus far incited unrest," National Police spokesman Abubakar Nataprawira told a press conference here.

    His remarks came just hours after thousands of officers raided the FPI headquarters just before dawn, resulting in the arrest of at least 58 FPI followers in connection with the Sunday's attack in which some 70 people were injured.

    The attack drew widespread condemnations, including from President Susilo Bambang Yudhoyono who on Monday ordered stern actions against those responsible for the brawl.

    Separately at the State Palace, National Police Chief Sutanto called on FPI's militia wing leader Munarman to turn himself in or face coercive measures.

    "He is the leader so he must take responsibility," Sutanto told reporters.

    Calls are mounting for the disbanding of FPI, which already gets a reputation for frequently vandalizing nightspots and pool houses.

    Minister of Justice and Human Rights Affairs Andi Mattalata has said the FPI was not officially registered as a public organization and therefore has no legal ground.

    Founded in August 1998, just four months after the resignation of longest serving president Soeharto who during 32 years in power gave zero tolerance to religious extremism, the FPI aims to uphold the Islamic law in the secular nation.
