«This group is taking the election momentum because democracy is not an ideology they follow. We ask the people not to go down the street [on May 22] as it would be dangerous. They would attack all masses including security apparatus.
«The arrest is a preventive strike,» Iqbal said displaying a number of items ceased in connection with the arrests, including five home-made bombs, red phosphorous of high explosive, four knives, bows and arrows. Police also presented 10 handcuffed suspects wearing black ski masks and orange prisoner uniforms.
The JAD network of almost two dozen extremist organisations has been implicated in numerous attacks in Indonesia in the past three years and was designated a terror organisation by the US in 2017.
Iqbal urged people not to hold street rallies and avoid mass gathering on the day for their safety.

Another police spokesman, Dedi Prasetyo, said police and military personnel would set up a security cordon around the headquarters of the Election Supervisory Agency and the Electoral Commission in downtown Jakarta.
Indonesia, the world’s most populous Muslim-majority nation, is an outpost of democracy in a Southeast Asian neighbourhood of authoritarian governments. It held the biggest single-day election on April 17 to elect a president and national and regional parliaments.
Vote counts from five independent survey groups showed incumbent President Joko Widodo with a clear lead over Prabowo Subianto, a general during the era of the Suharto military dictatorship who warned Indonesia would fall apart without his strongman leadership.
Subianto’s insistence that he was on course for victory, and his allegations of fraud, have led to speculation in some quarters that he might be trying to himself fix the results or would refuse to concede.
That would put pressure on the country’s democratic institutions and could possibly lead to violence.
His supporters recently held street rallies to call for fairness and vigilance in the vote counting, as the government warned that efforts to cast doubt on the outcome could amount to treason.
