KOTA TINGGI, MALAYSIA: Two murders have taken place in the state for the most peculiar of reasons.

One Myanmar worker was stabbed to death for ticking off a fellow colleague for being lazy at work while another man was killed by his brother over a sour plum.

Myint Aung, 31, was stabbed in the stomach and was found dead in a pool of blood in a house in Taman Anggerik in Bandar Tenggara.

Police caught three Myanmars in a forest about 2km away several hours after the stabbing.

However, the main suspect in the stabbing is still on the run.

In the second case, police arrested a 24-year-old man who stabbed his 20-year-old brother in a fight over a sour plum.

He said the man was detained until Sept 27.

Meanwhile, Johor police have obtained an extension on the remand of the four suspects detained in the kidnap and murder of Lai Ying Xin.

The extension is up to Sept 28. Police are waiting for the DNA test results.
