Thais have joined the worldwide craze for the ''Gangnam Style'' dance this year, but in a distinctly local style.
While the song's official music video ends with Psy's now ubiquitous horse-jockey dance, the Thai version of Gangnam has often ended with brawls.
The Gangnam Style dance has been blamed for at least two violent confrontations.
On the morning of Sept 21, Khlong Ton police were alerted to a shooting at a restaurant in Ekamai Soi 30.
At the scene, police found that a gang had opened fire on cars in the area, damaging the vehicles but causing no injuries.
Police found almost 40 spent shells at the scene.
Witnesses said the shooting erupted following a dispute over the Gangnam Style dance between two gangs.
Wacharin Gowan, 27, a member of one of the gangs, told police his group and the attackers, led by a man identified as Sonthaya, met in a pub in the Makkasan area and started arguing.
Both sides provoked each other with Gangnam Style dance moves.
Mr Wacharin said the pub closed, so his group moved to a bar in the Ekamai area. Mr Sonthaya's group arrived later and shot at them.
Police said they had identified the attackers and had sought warrants for their arrest.
The Gangnam dance triggered another brawl in November, this time in the northeastern province of Ubon Ratchathani.
On Nov 11, two young men were shot and wounded shortly after leaving a temple fair where they had performed the Gangnam dance.
Vorakit Chankong, 24, sustained a serious gunshot wound to his right eye. His friend, identified only as Nid, 17, was shot in the right arm.
Nid told police he and Mr Vorakit visited a temple fair in Muang district. The pair performed the Gangnam Style dance on stage. Their dance moves irritated a local teenager identified as Pichet Kullaket.
Pichet allegedly tried to attack the pair, but was kept away by a temple guard, according to Nid.
As they rode a motorcycle home about 2.30am they were confronted by Pichet, who allegedly fired shots at them and fled.
The Gangnam dance, however, also brought good news.
On Nov 27, inmates at Bangkok Remand Prison took up the dance to reduce stress and fighting among them.
About 4,500 prisoners joined a dancing competition. After one month of practising Gangnam style dance moves, quarrels among prisoners had declined significantly, corrections staff said.
''We have more unity as a result of the competition,'' said one inmate who was a member of the winning team.
