Umno rebels today pledged to hit the streets together with other activists at the #TangkapMO1 rally on Aug 27.

Gabungan Ketua Cawangan Malaysia (GKCM) vice chief Mohamad Zin Mustapa announced its support today and urged the public to also participate in the rally.

"GKCM would like to implore its members as well as the Malaysian public from all races to give full support to the youth and student movements for the peaceful TangkapMO1 rally on Aug 27 at 2pm.

"The time has come for Malaysians to stand up and be heard. This is not the time to stay silent.

"Support the youths so that the future of the next generation will not be pawned by Malaysian Official 1," he told a press conference in Kuala Lumpur today.

GKCM comprise Umno branch leaders opposed to Prime Minister Najib Abdul Razak, for which many have been expelled from the party.

The press conference was held back-to-back with Parti Pribumi Bersatu Malaysia's (Bersatu) press meet in Kuala Lumpur today.

Mohamad Zin said the US Department of Justice has highlighted various wrongdoings in 1MDB including those of "Malaysian Official 1".

He added that it was common knowledge who "Malaysian Official 1" is.

The DOJ believes more than US$3.5 billion was stolen from 1MDB and has moved to confiscate US$1 billion in assets allegedly acquired with the money.

It said at least US$731 million also went to "Malaysian Official 1".

The #TangkapMO1 rally seeks to call on the authorities to take action against "Malaysian Official 1".
