SRC International managing director Nik Faisal Ariff Nik Othman Kamil is among those who have been barred from leaving the country.
In its report today, The Star confirmed this with a check on the Immigration Department's website.
Nik Faisal has been implicated in allegations that RM2.6 billion had been deposited into Prime Minister Najib Abdul Razak's personal accounts.
He is wanted by the special task force investigating 1MDB. Nik Faisal ( photo ) and SRC director Suboh Mohd Yassin are supposed to give statements about Najib's accounts.
However, theSun reported today that both Nik Faisal and Suboh are missing. Citing sources close to the investigation, the daily said one of them is believed to be in Indonesia, while the other could not be traced.
The task force is also believed to be on the look out for business tycoon Jho Low.
Yesterday a managing director linked to SRC International was remanded by task force for five days to assist with the 1MDB probe.
The special task force has also raided the offices of 1MDB, SRC and two of its subsidiaries.
The travel ban on Nik Faisal comes amid reports yesterday that two opposition figures, Petaling Jaya Utara MP Tony Pua and Pandan MP Rafizi Ramli, as well as The Edge Media Group owner Tong Kooi Ong, have also been put under a travel ban.
The trio are being investigated under Section 124 of the Penal Code for alleged activities detrimental to parliamentary democracy.
It is not known if Nik Faisal is also being investigated under the same section.
