BANGKOK, Aug. 7 (Xinhua) -- An unexploded firebomb was discovered at a cloth shop in a Bangkok wholesale market on Wednesday.
Police told local media that the device was attached to a power bank charger for mobile phones, adding that the device was a similar type used in the coordinated bomb attacks in the capital last week.
Officials inspected the scene after the shop owner reported unknown power bank, found hidden under piles of clothes.
An Explosive Ordnance Disposal (EOD) team said it was a firebomb, triggered by a timer and set to explode on Aug. 2, the same day when a spate of bombings hit several locations across the capital.
However, the device failed to function properly. The police collected latent fingerprints for further investigation and checked surveillance camera footage in surrounding areas.
The newly-discovered firebomb is believed to be linked to the firebomb explosions at six locations in Pratunam and Siam Square areas.
Several bombs exploded in Bangkok on Aug. 2, injuring three people, as the capital hosted the 52nd ASEAN foreign ministers' meeting and related meetings.
