An unknown party fired a grenade from an M79 launcher into a parking lot within the Crime Suppression police compound in Bangkok's Chatuchak district at 4am yesterday, damaging a policeman's Honda Civic and a power pole.
The blast created a metre-wide hole in a temporary galvanised-tin fence.
Pol Colonel Supisal Pakdinareunart, acting division chief, instructed Phaholyothin bomb disposal and forensic police to comb the scene for evidence. Pol Lt-General Thangai Prasjaksattru, commissioner of the Central Investigation Bureau, also inspected the scene.
Police said they were not sure where the 40-millimetre grenade was shot from as the bureau's compound was an open area, with many possible launching spots including the condominium construction site behind the division's building and Motor Sport Land, formerly the Daen Neramit Amusement Park.
Police declined to provide further details to reporters.
The attack followed the bureau's request to the Criminal Court on Thursday to issue arrest warrants for 17 leading red-shirt demonstrators.
Meanwhile, the Criminal Court has issued arrest warrants for two suspects for allegedly being behind the Monday car bombing at Bangkok's Poseidon Massage Parlour and one for shooting a rocket-propelled grenade into the Defence Ministry compound, Metropolitan Police commissioner Lt-General Santhan Chayanont yesterday.
Following police investigation, the court granted the arrest warrants at 6.30pm yesterday.
In the Poseidon bombing case, the suspects were Akkaradech Sukkarat, who reportedly bought the car for Bt40,000 in Chiang Mai, as well as dark-skinned man, about 35 years old, who drove the vehicle to the scene. Police came up with a sketch of the second man from eyewitness accounts.
In the Defence Ministry case, the man wanted is Supanat Hurawet, who allegedly bought the Vigo pickup truck used in the attack from Songkhla's Hat Yai district before transporting it in a trailer truck to Bangkok. Supanat reportedly was arrested earlier for stealing a car in the jurisdiction of Provincial Police Region 1 and granted bail on March 10.
