Inspector-general of police Mohamad Fuzi Harun has advised all places of worship to install closed-circuit television (CCTV) cameras following several religiously-sensitive incidents.

"If there is any break-in, sabotage or theft, the police can automatically identify the individuals responsible for this.

"The installation of CCTVs may involve a high cost, but if they can afford it, they should install them," Fuzi told journalists during a function in Kota Bharu today.

On Feb 20, a 'datuk kong' idol was placed at a surau in Klang, causing outrage among the Muslim congregation. Three days later, two Hindu idols were placed at the same surau.

Police have since arrested a suspect who lives some 200 metres away from the surau. The suspect admitted to placing the idols at the surau.

Fuzi said police had a hard time solving the Klang case as there were no witnesses.

"But we were lucky that we got a lead, which allowed us to track the individual responsible," he said.

He urged police at the state levels to be vigilant of such incidents.

"We want the state and district police chiefs to monitor issues that can cause anger among the communities," Fuzi said.

"We hope the various communities will not take provocative action against the religions of others, particularly on the issue of Prophet Muhammad.

"The Muslim community must also understand the sensitivity of their non-Muslim friends," he added.

On Feb 10, police arrested a man for posting racially and religiously-charged comments on Facebook.
