An Indian man has been arrested in Kanchanaburi province for allegedly stabbing a Thai woman 31 times, killing her, at a hotel in Bangkok on Tuesday night.

The 32-year-old man and the 51-year-old Thai woman had been staying at a hotel on Soi Wutthakat 14 Road in Thon Buri district since April 7,  according to media reports. The woman usually stayed there during the day and left at night. She had a 20-year-old son.

On Tuesday a hotel employee reported hearing loud arguing in their room about noon. The employee called the room phone twice. Each time it was answered and immediately hung up. Shortly after 1pm the Indian man had walked calmly out of the hotel and drove off on a motorcycle.

Police were then called to the room. They found the Thai woman, Sukanya Disayabut, dead with 31 stab wounds. A blood-stained knife was also found in the room.

Police arrested Rajman Yabav in Kanchanaburi on Tuesday night. He was at Makarak Hospital for treatment for a large knife wound to his right arm.

Mr Yabav reportedly confessed to the murder and told police he acted out of anger.

Police were waiting for an interpreter, so they could question him more thoroughly.
