Bangladesh police has sent a letter asking Interpol to issue a red notice against fugitive accused Rabiul Islam alias Arav Khan, owner of Dubai's Arav Jewellers.

Bangladesh police has also been investigating the relationship between one of its senior officials and Arav Khan, said Inspector General of Police Abdullah Al Mamun.

He said this while replying to a query from reporters after inaugurating Enayet Bazar Police Outpost under Kotwali Police Station of Chattogram Metropolitan Police today.

"A letter has been sent to Interpol to issue a red notice against the name which is mentioned in the charge sheet in a case filed for murder of a Bangladesh police official," he said.

"A little while ago, I received the news that Interpol has accepted it. Now they will do the rest of the work," the IGP added.

When asked about the relationship of the senior police officer with Arav Khan, the IGP said, "We are looking into the case of a senior police officer. We'll let you know at an appropriate time."

Detective Branch of police on April 11, 2019 pressed charges against Rabiul and nine others in the murder case of Mamun Emran Khan, the then inspector of special branch of police.

In Dubai, he goes by the name of Arav Khan, which is an alias of Rabiul, said Shahidur Rahman, additional deputy commissioner of the Detective Branch (Khilgaon Zone) of Dhaka Metropolitan Police.
