Dubai, July 12 - Customs officials at the Dubai International Airport have foiled two bids of smuggling narcotics into the country and arrested two Asian passengers who concealed 80 capsules of heroin in their stomach, the WAM news agency reported Sunday.

The first attempt was aborted when officials at the airport forced a suspicious looking passenger to go through the body scan machine and found him hiding 50 capsules of the contraband drug. Initially, neither the X-ray detectors nor the manual search of his luggage revealed anything suspicious.

In the second case, the officials found another passenger hiding 30 such capsules in his stomach during the body scan, the report said.

Both passengers, whose nationality has not been revealed, were arrested and sent to the anti-narcotics department of the Dubai Police for further investigation and prosecution.

The United Arab Emirates (UAE) has a zero-tolerance policy towards narcotics and takes stringent measures to curb drug trafficking.
