The alleged beating of two teenagers by police officers in Klang will be investigated, inspector-general of police Khalid Abu Bakar said today.

"As usual, we will investigate," he said when met in Shah Alam.

Khalid added that the four police officers highlighted by DAP's Klang MP Charles Santiago may be suspended.

"If there are enough evidence that they are involved or they did that, by abusing (their) power and assaulting the kids, surely they will be charged," he said.

In his latest Facebook posting, Charles alleged that the "unrestrained violence" took place over the weekend, with at least four cops beating up two 14-year-old students while being interrogated at the Klang Selatan district police headquarters.

"The police personnel, including a woman officer, punched and slapped them on the face, hit them with a rubber hose, stomped on them, pulled their hair and caught them by their necks before slamming them against the wall and sofa.

"The woman officer threw her shoes at one of the boys and slapped him," he said in his post.

Charles alleged that the incident took place after police failed to get a remand extension for the two students, who were arrested after a gang fight outside their school.

"They were instead ordered to be released," he said.

Both of them are currently receiving medical treatment at Hospital Tengku Ampuan Rahimah after sustaining multiple bruises and scars on their bodies, Charles added.

According to the father of one of the students, M Paramasivan, the two had initially been beaten by other students last Wednesday.

The parents of the victims and the student who allegedly attacked them, lodged police reports that same day.

The following day, Paramasivan said police called his son and his companions back to the police station, and allegedly told them to retract their police report, which they did not.

Two days later on Saturday, the students who were attacked, were arrested, and allegedly bullied by the cops while in the lockup.

The next day, after the magistrate ordered them released, Paramasivan said the boys were attacked by police officers while having their statement taken.

"The inspector who was taking their statement was in the room, he saw them getting beaten, but did nothing," Paramasivan claimed.

He alleged the police were angry that the teenagers were represented by lawyers.

He also claimed that two other teenagers who were among those arrested on Saturday were also beaten, but were afraid to lodge police reports.

Paramsivan said that three of the four officers, who allegedly beat his son and the other student, had approached him at the Hospital Tengku Ampuan Rahimah, claiming they did not attack the boy.

"However, my son identified the three officers as among the four who beat him. The other boy also identified them," he said.

Meanwhile, Paramasivan also wants to know why the police had not taken any action against the student who allegedly attacked his son, and questioned if corruption was involved.
