Police suspect the attack on three security guard posts at a housing area in Klang, Selangor, last Saturday was by “rogue staff” with underworld connections who are working with a security company.

Inspector-General of Police Khalid Abu Bakar said the police were convinced there was an element of gangsterism at the incident in Bandar Bukit Raja, where a security guard was killed and six others injured.

Nevertheless, Khalid ruled out the security company as having links with secret societies.

"Let us carry out investigations. I do not believe the security company is involved with secret societies but I believe there are people working with the security company who are using such tactics," he said.

Khalid was speaking to reporters after the launching ceremony of the 1Malaysia People's Housing Programme (PR1MA) for police personnel in Kuala Lumpur today.

In the incident at 1.45am, a security guard was killed and six others injured when three guard posts in a housing area were attacked by a group of people linked to gangsters.
