Bahraini security forces stopped a British man of Asian descent on suspicion that he was carrying explosives on a plane coming to Bahrain in transit and headed to Britain," the interior ministry said on Twitter on Tuesday.
"After ensuring the safety of all the passengers and inspecting them and the airplane, no explosives were found aboard the plane and investigations of the suspect are continuing," the ministry said.
No further details were immediately available.
Pan-Arab news channel Al Arabiya said the flight originated in the United Arab Emirates. Al Arabiya said the man was taken off the plane in Bahrain's capital Manama in a hysterical or drunken state.
Witnesses said security forces had been deployed heavily around Bahrain International Airport.
But a government official said the airport had returned to normal operations. "The situation is under control," he told Reuters by telephone.
