An Indian passenger's passport was allegedly retained at Sharjah airport, because the passport control officer did not like his moustache.
Officials at the Sharjah Department of Naturalisation and Foreign Affairs are investigating the case, Gulf News reported.
Brigadier Dr Abdullah Bin Sahoo, Director-General of the department, said they will study CCTV images to check whether the passenger's allegations are correct and will then take action.
Sujeev Kumar, a software engineer, who flew from Thiruvananthapuram, Kerala, in India arrived in Sharjah on Friday.
Kumar said that the passport control officer told him he would return the passport if he shaved off his moustache.
He claimed that the officer stamped his passport, but did not return it.
