Her lawyer K Kumaraendran confirmed that she had left the building at 2.35pm through an alternative exit.

He told reporters the investigation was over, and that Rosmah had been asked to appear at the Kuala Lumpur Sessions Court at 3pm tomorrow.

“It is over now,” he said. “She has finished giving her statement and has gone back home now. That’s all.”

He declined to elaborate on the charges expected to be framed against Rosmah, asking everyone to wait until tomorrow.

Rosmah was summoned by the anti-graft officials for further questioning on the RM1.25 billion solar hybrid project for rural schools in Sarawak.

Whistleblower site Sarawak Report previously alleged that the solar panel project was awarded to the company without an open tender. It also claimed Rosmah’s husband, former prime minister Najib Razak, had endorsed the project to install solar panels in 369 schools.

Rosmah currently faces 17 money laundering charges involving over RM7 million under the Anti-Money Laundering, Anti-Terrorism Financing and Proceeds of Unlawful Activities Act 2001 and the Anti-Money Laundering, Anti-Terrorism Financing and Proceeds of Unlawful Activities Act 2001.

She claimed trial to all 17 charges on Oct 4.
