Police on Monday night arrested two adolescents who threw explosives at a traffic police kiosk at Asok-Din Daeng intersection, and seized numerous ping-pong bombs and similar items, Metropolitan Police Bureau spokesman Pol Maj Gen Jirasant Kaewsaeng-ek said.
The MPB spokesman said the two youths, whom he did not identify, were caught soon after by Thong Lor police, at 11.45pm.
The two said they had intended to join an anti-government demonstration at Din Daeng intersection, but when they arrived there on two motorcycles they found there was no rally.
So they hurled two small bombs at the traffic kiosk and fled, only to be caught shortly afterward.
Earlier on Monday night, police acting on a tipoff searched a spot in Soi Saeng Uthaithip near Opas Mansion in Din Daeng area. They found 15 improvised explosives and 13 ping-pong bombs.
There was a rally in Din Daeng by the Resistant Citizen group on Monday night, but that ended without incident, he said.
Pol Maj Gen Jirasant said police bleived three groups of protesters planned to rally on Tuesday evening.
The Silapin Phleng Pua Ratsadorn group would gather in front of the Klong Prem Central Prison about 4pm; the Resistant Citizen group in front of the Supreme Court about 5.30pm; and, the Thalugaz group at Din Daeng intersection about 5.30pm.
