Biman Bangladesh Airlines cabin crew member Mirza Adnan has been held for five days by the Abu Dhabi branch of the United Arab Emirates’ CID police while on duty in the country. A Sharjah station source said Adnan went missing from Sharjah Airport on July 22 and was later found to have been detained by immigration authorities after operating Biman flight BG-151.

UAE authorities have not explained the allegation or suspicion behind his detention. Biman acting general manager for public relations Muhammad Mohiuddin said immigration does not provide such information and may release him after an internal investigation or take action if an offence is established. Flight Operations Director Captain A K M Aminul Islam said he did not yet know about the matter.

According to the Sharjah station source, Adnan was transferred from Sharjah to Abu Dhabi CID for further investigation and questioning and remains in its custody. Sharjah station manager Zakir Hossain said Biman’s Abu Dhabi station and the Bangladesh embassy were informed by an Abu Dhabi police station. Abu Dhabi station manager Anwar Ul Firdaus said airport authorities and CID personnel would not provide any information despite contact.
