More than 10 people are under the scrutiny of the special task force investigating alleged misappropriation of funds in 1MDB, reported Sin Chew Daily .

The daily, quoting sources in the special task force, said those on the watch list included individuals from the business and financial sector as well as politicians.

It added that these individuals were being investigated and the authorities may move in to arrest them once there is sufficient evidence.

"Those on the watch list are not entirely from the top management but are from bottom to the top, including CEOs, directors and executives," the unnamed source was quoted as saying.

The report added, quoting the source, that subsequent arrests may involve bribery or abuse of power.

It said the special task force yesterday also visited an unnamed company to obtain important documents to facilitate its investigation.

The task force which comprises the Malaysian Anti Corruption Commission (MACC), police and Bank Negara, also refers to the Attorney-General's Chambers for guidance and legal advice.

The MACC today confirmed it arrested the director of a company at Kuala Lumpur International Airport (KLIA) yesterday to facilitate the task force's investigation.

Among the allegations being investigated by the task force is the RM2.6 billion which was said to have been deposited into the private bank accounts of Prime Minister Najib Abdul Razak.
