CCTV footage showed an Australian tourist getting stabbed at a Thai nightclub seconds after he upset a man — by pinching his girlfriend's bottom.

Jaydon Sienkiewicz, 21, had been drinking with 10 other friends and relatives inside a bar in Pattaya, Thailand, when he left to go to the toilet at 4 a.m. on June 7.

CCTV footage shows him standing next to a table when a Thai woman a few feet from him in a skimpy dress started twerking her backside towards him while wrapping her arms around her boyfriend.

Sienkiewicz is seen reaching across and pinching her bottom. The groping startled the woman who spun round to look what had happened.

Her boyfriend appears to become angry as she tries to restrain him, but he pushes her away and leans across a wooden railing to plunge a knife into Sienkiewicz's chest.

The young Australian lad clutches his wound and then staggers back to his table.

Police are now using the CCTV footage to try and track down the knife attacker after the incident at the Mixx Discotheque on the Walking Street area of the tourist resort.

They visited Sienkiewicz in his hospital bed where he was given 5,000 THB (115 GBP) to aid his recovery.

Police issued an arrest warrant for the Israeli attacker, but he is believed to have fled the country at 10 a.m., just six hours after the attack.
