Songkran foam parties have been banned this year in the interest of public safety, national police deputy commissioner Pol General Chalermkiat Srivorakan said on Friday.
Chalermkiat said there had been several deaths and injuries by electrocution at foam parties during previous Songkran festivals.
He said that police have also been instructed to provide security at Songkran celebration venues and not to collect bribes from foreign migrant workers travelling back to home countries during Songkran.
Metropolitan Police Bureau deputy commissioner Pol Maj General Sukhun Phrommayon said that nearly 2,000 police officers and related officials will patrol 49 Songkran celebration venues across the city where 128,900 revellers were expected.
Some 60,000 revellers were expected to celebrate in Silom Road area, and 14,000 at the Royal City Avenue (RCA), 10,000 at the "S2O" event on Rama 9 Road, 5,000 at "The Street Ratchada" mall, 5,000 at Central World and 5,000 at Siam Square, he said.
Sukhun also urged revellers not to wear "too revealing clothes" to help prevent sexual harassment and said people should pour water and put powder on others appropriately in keeping with good Songkran tradition. As for those travelling upcountry during Songkran, the city police would implement a home-watch scheme to ensure their houses were safe.
