A joke between friends led to a bomb scare at Bangkok's Suvarnabhumi International Airport Saturday, according to the web edition of local newspaper the Nation.

Police and soldiers rushed to arrest a man at the Gate 7 on the fourth floor of the outbound passengers building at 8:30 am (0130 GMT) after receiving reports from a security officer on radio that the man might be carrying bombs in his bag.

But police failed to find any explosive on the man who declined to be identified.

The man said the scare was apparently caused by a misunderstanding. He said he earlier joked with a friend, who is a security officer, that he was carrying two bombs.

The man said other security officers might overhear the joke and thought that he was making a bomb threat.

Security at all public transport locations in Bangkok -- from bus stops and stations, the railways, the metro and Skytrain, to Suvarnabhumi airport -- has been tightened following the coordinated explosions in the city on New Year's Eve.
