Police held a meeting on Wednesday night to analyse how thieves managed to open the reinforced door of an armoured vehicle and make off with two bags containing Bt6 million.
After the meeting at Bang Yai Police Station in Nonthaburi at 8.30pm, Pol Maj-General Suwat Jaengyodsuk, Provincial Police Bureau 1 acting commissioner, admitted that police were still in the dark how the thieves had managed to open the door of the Brinks vehicle.
He said investigators were still not sure whether two security officers with the company were involved in the heist.
The theft took place at 10pm outside the Central West Gate shopping mall in Nonthaburi’s Bang Yai district.
The truck was being driven by Somyos Kham-oon and guarded by security officer Namchai Jinoo.
The two parked the truck on the roadside to pick up a deposit from a True shop in the mall.
The men told police that when they returned to the truck, they found the door open although they had locked it. They also reported that two bags each containing Bt3 million had disappeared but 11 other bags were still in the truck.
Police checked the truck and did not see any signs of the door being forced open.
Suwat said footage from security cameras in the area showed a pickup driving near the armoured vehicle several times but did not reveal how the thieves opened the truck’s door.
