Federal commercial crimes director Amar Singh has advised former Federal Territories Umno Youth chief Razlan Rafii not to make "tin kosong " (empty vessel) statements.

“At this time, the court case (involving former prime minister Najib Abdul Razak) is related to the SRC International funds and not 1MDB.

“He (Razlan) can say what he wants as long as it does not violate the law,” Amar said, adding that the police are exercising their duties with regard to the 1MDB investigation without taking sides.

“We are also doing our duties without fear and in a professional manner,” he was quoted as saying by Berita Harian.

Yesterday, Razlan warned Amar and MACC to stop talking about 1MDB in view of the temporary gag order issued by the High Court in Kuala Lumpur.

"MACC and Amar: Stop talking about 1MDB. Don't let the media judge Najib. I am warning you.

"Don't be so eager to talk about this and that list, about the millions seized... RM1.1 billion. There is no truth to these negative matters and it prejudices Najib in the eyes of the people.

"Whether he is guilty or not, let the courts decide. Civil servants shouldn't play this perception game," Razlan had said.

On Wednesday, Najib was charged with three counts of criminal breach of trust and one count of abuse of power in relation to funds from SRC International.

The court later allowed an application by the former prime minister's lead counsel, Muhammad Shafee Abdullah, for a temporary gag order on the case.

Previously, police teams led by Amar had confiscated cash, handbags, luxury watches, sunglasses and jewellery with a combined estimated retail value of up to RM1.1 billion from Najib’s house and properties linked to him.

Among the jewellery found were 1,400 necklaces, 2,200 rings, 2,100 bangles, 2,800 earrings, 1,600 brooches and 14 tiaras.

Najib has said that the items were mainly gifts to him and his family and not linked to the funds missing from troubled state-owned company 1MDB.
