A 19-year-old man was killed and four others hurt in a brawl at a rock concert in Pathum Thani's Klong Luang district yesterday, police said.
Sarawut Jit-o-larn instantly died from three stab wounds while his four friends, aged 17 to 19, were hurt.
The teenagers were attacked at around 12.30am at the Paradox concert on a field near the site of an August condominium collapse, said Captain Thawatchai Dech-upakan of Khlong 5 Police Station.
Tawan Lek-kla, 18, told police that his group had an argument at the concert with another group of teenagers whom they had never met before.
Tawan, who was slashed on the ankle, said the argument quickly turned violent, with the other group attacking them with knives before fleeing.
Police later announced the arrest of three suspects, aged 17 to 22, along with the seizure of three knives.
Khlong 5 Police Station deputy superintendent Lt-Colonel Krissadaporn Panprong said the concert’s organisers had asked for police permission to stage the event and 50 officers were stationed there.
He insisted that police searched concert-goers but some teens were still able to smuggle knives into the venue.
