A man died after falling into a 15-metre-deep tube well on a road divider in Bangkok's Lat Phrao district on Friday.

City inspectors, known as thessakit, saw the man, whose identity has yet to be confirmed, falling into the well at Soi Lat Phrao 49, police said. The incident was reported at 11.13am.

Rescue workers rushed to the scene, as police closed traffic on both lanes of the road.

At 12.10pm, the man was successfully retrieved, but he was dead.

According to reports, the victim was crossing the road when he stepped onto the wooden cover of the Metropolitan Electricity Authority's tube well, causing it to give way and resulting in his fall.

Bangkok governor Chadchart Sittipunt said the Bangkok Metropolitan Administration extended its condolences to the victim's family.

Mr Chadchart said the loss of life was due to an electrical conduit whose cover was not completely closed.

The Wang Thong Lang district office had notified the agency concerned to repair its electrical conduit three weeks ago, said the governor.

The BMA was ready to work with the MEA to provide compensation to the family, he added.
