This is the moment two crazed fans slip through airport security to stalk a Korean actor.

The two women, aged 38 and 25, borrowed security guards from staff they knew and dressed in their uniform before walking into Suvarnabhumi Airport in Bangkok, Thailand, last Friday (14/09) night.

They were in pursuit of Korean pop star Lee Jong-suk who had arrived at the airport on a flight from Seoul.

The pair are CCTV entering a ''highly secure'' restricted staff area for pass holders - before walking into the baggage collection and customs area.

Wearing a grey top, left, and black dress, right, and with ID cards around their neck, they then join the entourage of airport staff escorting the actor.

The crime - which raises alarming questions about security at one of the world's busiest airports - would have gone undetected.

But the giddy women posted pictures and details of their endeavours on Instagram which found their way back to the authorities.

The woman, who has not been named, wrote alongside pictures of her in the airport she was the first person to shake the star's hand.

She said: ''Thanks Piano, my lovely friend for looking up Jong-Suk’s flight. Thanks to Sai for taking me inside the arrival hall! I was the first who shook hands with him! My, my, my. I won’t wash my hand.''

The customs department said on Tuesday that it is now seeking trespassing charges against the two fans.

The airport’s police chief, Colonel Viroj Tudso, said that summonses had also been issued for two customs officers accused of helping the fans enter the area.
