Selangor police chief DCP Datuk Khalid Abu Bakar said this was to enable his personnel to monitor the houses closely during the absence of the dwellers. He said there was a special form available at all police stations which was also being distributed to houses for residents to fill for this purpose.

He said past records showed that this practice reduced crimes dramatically as police intensified their patrols in places where residents were not around.

Speaking at the launch of the "Balik Kampung, Rumah Selamat" campaign jointly organised by police and resident associations in Subang Jaya and held at the Sunway Pyramid today, Khalid urged residents to be vigilant and enhance the spirit of neighbourliness to fight crime.

He said all residents of Selangor should keep the state police hotline number (03-2052 9999) handy or memorise it as it will be useful during emergencies.
