An elderly taxi driver has been found dead at the bottom of a storm drain after stopping to urinate down it and falling in.
Suwan Phromnok was found in a fetal position with water up to his chest in the bottom of the hole, which measured just one metre by half a metre across.
The 64-year-old, originally from Nakhon Ratchasima, fell down the drain, which had no grate and was surrounded by tyres, at a petrol station in the Thai capital, Bangkok.
The cabbie's wife 67-year-old Lauei Muenjai believed her husband had gone to the gas station to repair his taxi at around midday.
She said it was likely he started drinking with friends while the work was taking place - but when he realised it was not going to be fixed until the next day, he started walking home in the dark.
Mrs Muenjai believes he would have stopped to go to the toilet in the open drain and probably fell in while drunk.
Police lieutenant Ekachai Innimit told reporters that Mr Phromnok's body was sent to Siriraj Hospital for a post mortem examination to determine his cause of death.
The police will review CCTVs in the area to gather evidence to see if his wife's theory on his death was correct.
Bangkok invested heavily in the creation of new water drainage infrastructure following the devastating flooding of the city in 1983.
But due to its wet climate, flooding is common in Bangok and as a result, storm drains are everywhere in the city.
