Pontian MP Ahmad Maslan and former Johor Bahru MP Shahrir Samad have been arrested by the MACC.

The duo will be charged tomorrow at the Kuala Lumpur Sessions Court.

"Shahrir and Ahmad will face one and two charges respectively under the Anti-Money Laundering, Anti-Terrorism Financing and Proceeds of Unlawful Activities Act 2001," the MACC said in a statement today.

The MACC said Ahmad was arrested at 10.10am while Sharir was detained at 11.22am.

It said both were arrested after presenting themselves at the MACC headquarters in Putrajaya.

They were subsequently released on MACC bail. 

The commission did not elaborate on their alleged offences.

However, both were previously implicated with receiving money from former prime minister Najib Abdul Razak, whose source of funds was allegedly misappropriated from 1MDB.

According to Najib's bank accounts money trail, Ahmad received RM2 million from Najib's bank account ending 906 on Nov 27, 2013.

On Nov 28, 2013, Shahrir also received RM1 million from the same bank account.

Shahrir had in August 2015 defended taking money from Najib when the money trail became public.

"Who else should I ask for financial aid for expenses in running my (party) division, if not from my own party president," he had said.

A month before that, Ahmad also defended the source of Najib's funds, insisting that they were not misappropriated from 1MDB.

Ahmad served as the deputy finance minister and later the deputy international trade and industry minister under the previous BN government.

Shahrir was the domestic trade and consumer affairs minister between 2008 and 2009. He also served as the Felda chairperson under the previous government.
