SUBANG JAYA, May 12 — Former prime minister Datuk Seri Najib Razak and his wife Datin Seri Rosmah won’t be flying to Indonesia today, a police source told Malay Mail.

According to the source, the private flight that was supposed to depart from the Sultan Abdul Aziz Shah Airport here for Jakarta at 10am has been cancelled pending further instructions, following the appearance of a mob earlier.

"It’s due to security reasons and the crowd here this morning.

"We still need to ensure the security of everyone. Emotions are running high and we can’t allow the public to take matters into their own hands,” the source who spoke on condition of anonymity said.

Some 100 people gathered outside the airport at about 9.30am today, waiting for the arrival of Najib and Rosmah who were to be fly on a private jet operated by Premiair and owned by Indonesia’s 14th richest man and head of PT Rajawali Corp, Tan Sri Peter Sondakh, to Jakarta.

The multiracial crowd surrounded passing cars, blocking their passage and demanded to see the occupants within by banging on the car roofs and trying to peer through the heavily-tinted windows.

Perlis Barisan Nasional chief Datuk Seri Shahidan Kassim who was in a white Toyota Vellfire was among those mobbed, but was let through after winding down his window and showing his face to the angry crowd.

The police source said Shahidan was scheduled to fly back to his hometown.

One man who banged on Shahidan’s car was heard shouting that the people had the right to know who was entering the airport premises.

"We’ve waited 61 years for a change. We have the right to know who is in these cars coming in. We want to know if it’s Najib!” he demanded.

The man refused to give his name when Malay Mail approached later, only saying he was a Subang Jaya resident.

Police personnel, including a light strike force unit, were deployed to control the situation after the mob started harassing motorists.
