Home Minister Datuk Seri Hishammuddin Hussein said today the opposition pact must ensure that the assembly they propose to hold on Saturday does not develop into a riot.

They should apply to Stadium Negara if they wish to organise the assembly there and ensure that the capacity stipulated was complied with, he said.

He said everyone must ensure that the assembly did not turn into a riot as had happened during the 'Bersih' gathering last year.

In this context, Hishammuddin hoped the organisers would hold a meeting with the police on the security measures that must be adhered to.

"I am convinced that the Inspector-General of Police had monitored the situation and can ensure that what we fear will not recur. What is important now is that we learn from what had transpired at the Bersih gathering previously where there were chaos and street rioting," he told reporters here, after a briefing on the Barisan Nasional's preparations to face the 13th general election.
