POLICE ARE looking for a group of 10 people including a woman who are likely linked to the mysterious homemade bomb that killed two men in Min Buri district last Saturday.
Another clue is a white van seen by witnesses accompanying a motorcycle the two dead men were travelling on before the pipe bomb went off, killing them at the scene near Soi Rat Uthit 12, Pol General Aek Angsananont, deputy National Police chief, said yesterday.
The van, bearing a licence plate with the number 744 but unknown letters and province of registration, was seen fleeing after the explosion.
The police investigation is taking three directions – the explosion that killed the two men, who were found to be staying in the neighbourhood; the discovery of explosives and all bomb-making material; and photos of people that rented the house, which could lead to the identification of at least five of them, as well as footage of the suspicious van.
Latent fingerprints have also been collected that match some people with criminal records, who are likely some of the suspects found to have stayed in the rented house during the time the pipe bombs were assembled, Aek said. Police found that there were four stolen motorcycles parked at the house rented by the 10 people and learned that the times of the thefts were close to each other.
The 10 people began using the house on March 9, which was shortly after two pipe bombs were planted at a judicial institute and the nearby Attorney-General’s Office compound.
“The bombs found planted at the two locations were assembled like those five pipe bombs found in the rented house,” Aek said.
Pol Colonel Kanchol Inthraram, chief of Min Buri police, said there was no concrete proof that the rented house had been used as a bomb factory.
The house was in an open area and any bomb-making activity would have been easily noticed by neighbours. However, the forensic investigation would continue to try to uncover more evidence.
“The house was used rather as a site to store explosives or the pipe bombs, not to assemble them,” he added.
Two of the four motorcycles were found to have been stolen from Pattaya in Chon Buri and Samet in Rayong early last month.
The van is painted solid white and had no glass windows. Police are checking into its licence plate.
