A SINGAPOREAN engineer was stabbed to death in his home in Lombok, Indonesia, on Saturday night.
An Indonesian man has been arrested over the killing.
The Singaporean, Ahmad Suri, 52, was a deputy manager of an Indonesian engineering firm and had been working in Mataram city on Lombok island for two years, said his younger son, Mr Abdul Rahim Ahmad, 27.
The father-of-two was found dead in his terrace house on Saturday after his neighbours heard shouts coming from the home.
"(Neighbours) ran over and saw the suspect holding a knife outside my father's house. He didn't try to run, so they took the knife and held him down," said Mr Rahim, who was told what happened by his father's neighbours.
Mr Ahmad was rushed to the hospital in a taxi but died on the way. He had been stabbed seven times in the head, neck and chest.
Indonesian police said the suspect is a 30-year-old transmission tower climber called Suparto.
Mataram police's head of criminal investigation, Agus Dwi Ananta, told The Straits Times the murder was not premeditated.
"The suspect usually walks alone after work, with his work tools, including a knife and other accessories," he said, adding that police were interviewing five witnesses and waiting for the results of a post-mortem.
It is unclear what sparked the attack, but the Indonesian Kompas news daily said Suparto was supposedly visiting his wife and child, who were living in the same house as Mr Ahmad.
