The fans ran riot in the stadium after the referee decided not to let Arema's 71st-minute equaliser stand, prompting the game to be called off.

Persiwa had earlier taken a 2-0 lead through Mariano Oscar Sorrentino in the 27th minute and Pieter Romaropen midway through the second half.

Cameroonian Emile Mbamba hauled the two-time Copa winners back into the game a minute later (68), only for an equaliser to be ruled out, sparking mayhem.

League officials have yet to decide what action will be taken against Arema and their fans.

Newly crowned Copa Indonesia winners Sriwijaya Palembang were held to a 2-2 draw by 10-man PSMS Medan in the other Group A match on Wednesday.

Liberian playmaker James Koko Lommell opened the scoring for PSMS after only 52 seconds at the Brawijaya Stadium, finishing from a fine lobbed pass from his midfield partner Argentinian Gustavo Chena.

Lommell extended the Sumatran side's lead in similar fashion in the 29th minute when he again converted from a Chena lob.

Sriwijaya reduced the deficit shortly before half-time when defender Ambrizal seized on a rebound, and PSMS were then dealt a blow when full-back Supardi was dismissed for a second bookable offence in the 49th minute.

His side were unable to hold on to their lead and Sriwijaya made the most of their numerical advantage by equalising in the 67th through a long-range strike from Zah Rahan.

The Group B play-off, which is being played at Manahan stadium in Solo, comprises Persija Jakarta, Persipura Jayapura, Deltras Sidoardjo and defending champions Persik Kediri.
