The man was identified Shakthivel, 26, a resident of Noida of West Bengal in India, according to information on his passport.
Sources at the airport said the counter staff became suspicious of the visa when Shakthival went to the check-in counter of Biman Bangladesh Airlines for boarding and contacted the Immigration Liaison officer at UK High Commission.
After scrutiny, the immigration liaison officer confirmed that the UK visa was forged. Shakthival was handed over to the airport armed police pending further legal action.
Alamgir Hossain, additional superintendent (ops and media) of AAP, said he was handed over to the Airport Police station where a case was filed against him on early Monday.
Sources at the Immigration police said Sakhtival entered Bangladesh through Benapole on January 20.
