A British man is in police custody today suspected of killing a Thai woman with a machete in the early hours of Thursday at his home in Pattaya.

46-year-old Neil Henry Elliot from Northern Ireland was detained by hospital staff where he was taken for treatment following a motorbike accident he was involved in after fleeing the scene of the murder.

In what was described as a state of delirium, Elliot admitted murdering a woman at his home as he was being treated for his injures prompting hospital staff to alert police.

After speaking to the Brit, officers from Bang Lamung Police Station visited a townhouse in Eakmongkol Project 4 where they found blood all over the floor before discovering the body of a woman in the bathroom.

The woman was identified as Miss On, aged between 35-40. She had been slashed multiple times on the neck and wrists.

A bloodstained machete about 60cm in length and a broken pool cue, also covered in blood, were found in the house.

Elliot later told investigators he met Miss On earlier on Thursday night on Soi Buakhao before the couple returned together to his townhouse where they both took yaba.

Details of why the couple became involved in a physical confrontation were not made clear nor was any reason why Elliot attacked the woman with the pool cue and a machete that led to her death.

Elliot has been remanded in custody while the investigation continues.
