The incident occurred at a house in Felda Bukit Easter in Kota Tinggi, Johor, at about 8.45am on Thursday, Sinar Harian reported.

Kota Tinggi district police chief Hussin Zamora said the family allowed the 30-year-old man to use the toilet.

“Later, the house owner’s son saw him trying to enter one of the rooms. When they tried to stop him, he got aggressive and used a machete he found in the house to attack them,” the Malay daily quoted him as saying.

“Neighbours heard the screams of the house owner’s wife and rushed over to help. They held the suspect until police arrived.”

Hussin said the 60-year-old house owner and his son suffered minor injuries and were given outpatient treatment at a hospital.

“The suspect was also injured and taken to hospital,” he said, adding that a urine test found him positive for methamphetamine.

He said the suspect had two drug-related records.
