The Chief Metropolitan Magistrate court in the Bangladeshi capital Dhaka issued an arrest warrant for Abdul Latif Siddique for allegedly "wounding religious sentiments" of the country's majority Muslim population, police inspector Aminur Rahman said.
"The arrest warrant has been sent to a police station in his hometown," Rahman told AFP.
Siddique, formerly an influential minister in the cabinet of Prime Minister Sheikh Hasina, accompanied her last month on a visit to New York where he spoke out against the Hajj pilgrimage as well as against a non-political Islamic group, the Tablig Jamaat.
"Two million people have gone to Saudi Arabia to perform Hajj. Hajj is a waste of manpower. Those who perform Hajj do not have any productivity," he said in the TV footage.
"They (Hajj pilgrims) deduct from the economy, spend a lot of money abroad," he said.
The comments drew immediate fire back home from the hardline Islamist group Hefajat-e-Islam whose leaders called him "an apostate" and set a 24-hour deadline for the government to dismiss him from the cabinet.
If he is loses his party role, Siddique will also automatically lose his seat in parliament.
At a New York rally where Siddique was the lone speaker, TV footage also showed him making critical comments about Hasina's influential son and technology adviser, Sajeeb Wazed Joy. "Who is Joy? Joy is not part of the government," he declared.
Siddique, who is now believed to be staying in Kolkata, has since appeared to retract his comments about Joy, saying the premier's son represents "the future of the country".
The arrest warrant means Siddique may have to extend his stay abroad to avoid prosecution or seek exile like author Taslima Nasreen, a self-declared atheist who now lives in India after fleeing Bangladesh in 1994 when one of her novels triggered protests by Islamists who threatened her life.
