Seremban district police chief Yatim Osman said the 50-year-old was arrested in front of his house here at 11.45pm.

He said a 49-year-old woman who works as a trader was travelling in a Perodua Bezza with her husband at about 6pm when they realised they were being followed by a silver Honda Accord.

“The car, driven by the man, then overtook and abruptly blocked the victims’ vehicle. The man got out and attempted to provoke the couple, and took something from the rear of his car.

“The man then sprayed an eye irritant at the victims, causing irritation and itchiness to their eyes. They claimed they did not know the man and are unaware of his motive,” he said in a statement here today.

Yatim said both victims sought outpatient treatment at Tuanku Ja’afar Hospital and are in stable condition.

He said police seized a black canister of eye irritant bearing the word “Police”, believed to have been used in the incident.

The suspect, who has a record of three drug-related offences, tested negative for drugs.

The case is being investigated under Section 324 of the Penal Code and Section 6(1) of the Corrosive and Explosive Substances and Offensive Weapons Act 1958.

Yatim said police applied for a remand order against the suspect at the Seremban court today to facilitate investigations.
