DHAKA: Bangladesh police were Sunday searching for a man who defied a ban and married a Rohingya refugee, hundreds of thousands of whom have fled across the border to escape violence in Myanmar.

More than half a million Rohingya refugees have flocked to Bangladesh since an army crackdown began on August 25 in Myanmar's Rakhine state, a process the UN has described as ethnic cleansing.

Shoaib Hossain Jewel, 25, and his 18-year-old Rohingya bride Rafiza have been on the run since marrying last month, said police in Jewel's home town of Singair.

"We heard he married a Rohingya woman. We went to his home at Charigram village to look for him," Singair police chief Khandaker Imam Hossain told AFP.

"But we did not find him there and his parents don't know where he has gone," he said, adding they were investigating the case.

In 2014 Dhaka banned marriages between Bangladeshis and Myanmar's Rohingya Muslim refugees following claims that members of the persecuted community were attempting to wed to gain citizenship in the mainly Muslim nation.

Jewel's father Babul Hossain said citizenship was not the motive this time and defended his son's marriage to Rafiza.

"If Bangladeshis can marry Christians and people of other religions, what's wrong in my son's marriage to a Rohingya?" Hossain told AFP.

"He married a Muslim who took shelter in Bangladesh."

The Dhaka Tribune newspaper said Jewel, a teacher in a madrassa or religious school, fell in love with Rafiza after her family fled the latest bout of violence in Myanmar and took refuge at a cleric's house in Singair.

In a police crackdown, the family was forced to move back to the main refugee camp in the southeastern district of Cox's Bazar -- some 265 miles from Singair.

A lovestruck Jewel rushed to Cox's Bazar, running from one camp to another in search of Rafiza. He finally found her and asker her parents for their daughter's hand in marriage.

Their wedding in Cox's Bazar was the first known one between a Bangladeshi and a Rohingya refugee since the August flare-up, the newspaper reported.
