BANGKOK - Bank robbery suspect David James Roach is still being held at an immigration detention centre in Bangkok, a week after he was detained by Thai police for allegedly making off with some $30,000 from Standard Chartered bank on July 7.

According to Thai police immigration police chief Nathathorn Prousoontorn, police are still waiting for a court decision on whether the Canadian national can be extradited to Singapore to face charges.

However, as the Kingdom is having a public holiday from Monday to Wednesday (July 18 to 20), any decision on this may only happen after that.

The 27-year-old was arrested in Bangkok on July 10, three days after he allegedly robbed about $30,000 in cash from a Standard Chartered bank branch in Holland Village.

He had left his home in eastern Canada to backpack across the world a year ago, and was apparently on his first visit to Singapore when he allegedly carried out the first successful bank robbery here in more than a decade.

He is alleged to have walked into the Standard Chartered Bank branch ​at around 11.30am on July 7, handed the teller a slip of paper with his demands, and slipped away with the loot in just minutes.

The same day, he fled Singapore for Bangkok.
