The Malaysian passport of businessperson Low Taek Jho has been invalidated, Immigration Department chief Mustafar Ali said today.

This comes after Low refused to heed requests by the Malaysian authorities to return to Malaysia to assist investigations into the 1MDB affair.

According to The Star Online, Mustafa said the cancellation of Low's passport was initiated through a request by the MACC on June 15. 

However, invalidating the businessperson's passport is unlikely to stop him from international travel as he reportedly also holds a passport from St Kitts and Nevis.

St Kitts and Nevis is a small tropical island state east of Puerto Rico. The country has the land mass about the size of Kuala Lumpur.

The country is popular among those seeking a second passport because it does not have residency requirements.

Foreigners can obtain citizenship in return for real estate investment of at least US$400,000, or a contribution of at least US$250,000 to the state’s sugar industry diversification fund.

A quick Google search revealed some agents were advertising St Kitts and Nevis passport packages for as low as US$150,000 (RM606,750).

How Low, better known by his moniker Jho Low, managed to evade the authorities over the past few years is unsure given that Singapore had secured an Interpol red notice against him.

Prime Minister Dr Mahathir Mohamad said that he was likely to be residing in a country from which he cannot be extradited.

Low is believed to have played a pivotal role in 1MDB affairs beginning with its predecessor Terengganu Investment Authority (TIA).

He is also a person of interest in the US, where authorities claim US$4.5 billion in funds misappropriated from 1MDB went through the country's financial system.
