Karnataka state authorities have blamed Royal Challengers Bengaluru (RCB) and its partners for a fatal stampede during last month’s IPL victory celebrations, Al Jazeera reported.

According to a report released Thursday, the team held a parade in Bengaluru on June 4 without formal police permission, despite a rejected request. The event drew massive crowds near M Chinnaswamy Stadium, resulting in a stampede that killed 11 people, aged 14 to 29, and injured over 50 others.

The report cited poor planning and lack of coordination by RCB, event organisers DNA, and the state cricket association. Four individuals, including a senior RCB executive, have been detained in connection with the incident, according to Al Jazeera.

RCB has not commented on the findings.
