Thai police said they discovered bomb making materials during raid of second apartment on the outskirts of the capital.
The authorities increased their circle of investigation in search of suspects involved in Bangkok’s deadly bombing.
National police chief Prawuth Thavornsiri said that police found fertiliser, gun powder, digital clocks and remote-controlled cars whose parts can be used for detonation, among other items, during a raid over the weekend at an apartment in Bangkok’s Min Buri district.
He said these are bomb making materials and nobody would keep urea fertiliser and gunpowder unless they wanted to make a bomb.
Saturday’s arrest was the first possible breakthrough in the investigation into the Aug. 17 blast at the Erawan Shrine, which killed 20 people, more than half of whom were foreigners, and injured more than 120 others.
Authorities have dodged questions about whether the suspect is believed to be Turkish, saying that he was travelling on a fake passport.
Images circulated online after his arrest of a fake Turkish passport with the apparent suspect’s picture.
“We don’t know if he is Turkish or not,” Prawuth said Saturday.
