Malaysian immigration officials told AFP they were unaware of the passport cancellation and said Waythamoorthy should return home to check the status of his travel document.
But Waythamoorthy said Kuala Lumpur intended to force Britian to deport him so he could be arrested under Malaysia’s Internal Security Act (ISA), which allows for indefinite detention without trial.
Waythamoorthy, along with his brother P Uthayakumar and four other Hindraf leaders, angered the government in November by mounting a mass rally alleging discrimination against minority ethnic Indians.
Waythamoorthy fled Malaysia in December to lobby the international community for support, while the other five were detained under the ISA.
The Federal Court on Wednesday refused to release the five.
Amnesty International’s Asia-Pacific advocacy director T Kumar called on Malaysian Prime Minister Abdullah Ahmad Badawi to give a “full explanation on the rationale for the cancellation.”
“This is the first time I have heard of a political activist’s passport being revoked by his own country’s government,” he told AFP.
