A group of parang-wielding men stormed a police station in Labis, about 150km from here, and attacked a man who had earlier rescued a constable.
Policemen rushed to help the victim and arrested the five intruders in the 11am incident yesterday. They also seized four machetes.
Earlier, it is learnt, one of the suspects had stopped a car carrying the constable, his wife and two friends along the Labis-Segamat trunk road.
When the policeman got out of the car, one of them slashed him in the back.
One of the policeman's friends quickly pulled him back into the car and they sped towards the Labis police station, several kilometres away.
The five suspects followed in another car and entered the police station where they started to attack the constable's friend.
Johor CID chief Senior Asst Comm Datuk Dr Hashim Haron said the victims, in their 40s, had been admitted to the Segamat Hospital to treat their slash wounds.
“The five suspects are aged between 30 and 40,” he said.
SAC Dr Hashim said the incident might have been due to an old grudge or personal problems between the constable and one of the suspects.
