Razarudin said the incident occurred at 5.30am today and police were tracking down the suspect with the help of the Kuala Lumpur City Hall (DBKL).

“In the incident, the suspect, who was riding a motorcycle, had made some noise before hurling stones at the glass wall of the building.

“Guards on duty in the building witnessed the incident.

“Police are tracking the suspect and, Insya-Allah, we will track him down soon,” he told a special media conference on Ops Cantas in conjunction with the state elections in Bukit Aman here today.

Police are reviewing the close-circuit television (CCTV) cameras in nearby areas to assist in their investigation to identify the suspect.

According to him, the case is being investigated for committing mischief.

Earlier this morning, PAS lodged a police report after one of the glass walls in the PAS headquarters was broken by stones hurled by a man just a few hours before the nomination process for the six state elections began.
