Most of the shots were aimed at the burial ground but at least two shots hit two cars -- one shattering the back windscreen and another hitting the bonnet of another passing motorist.

The police constable also fired three shots into his own car.

It is learnt that the two motorists, who were going back to Kota Baru for Hari Raya, lodged reports at the Kota Baru police station.

The 22-year-old police constable, meanwhile, was nabbed by a police team from Kuala Lipis who surrounded the suspect and spent several minutes talking to him before he eventually dropped his revolver.

The case is now being investigated by police from Pahang and Negri Sembilan who are among others, trying to ascertain how the suspect, who was on Hari Raya leave, was allowed to take his service revolver with him.

They are also trying to find out how he had more than 60 bullets in his possession.

The drama unfolded about 6.30am when the suspect, a general duty policeman with the Simpang Durian police station in Jelebu, Negri Sembilan, was on his way back to his hometown in Rantau Panjang, Kelantan.

He stopped by the road shoulder at Kampung Selindung before getting out of his vehicle and began shooting randomly.

Kuala Lipis district police chief Superintendent Abdul Razak Hassan confirmed two shots hit two passing cars, adding that the two motorists were not hurt.

Abdul Razak said they were informed of the incident by passing motorists who were alarmed at seeing the man firing his revolver.

"The suspect was sent to the Kuala Lipis Hospital for psychiatric evaluation," he said.

Meanwhile in Seremban, state police chief Datuk Osman Salleh said stress could have driven the policeman to open fire.

"To date, we do not know the actual reason why he fired the shots.

It could be due to stress or personal problems," Osman said.

He added that the constable had been with the force for three years and had no past disciplinary records.

Osman said he had also directed the Jelebu district police chief to investigate the matter, especially how the policeman managed to take home his service revolver which should have been left at the police station.
