Selangor police chief Hussein Omar Khan said the couple, in their 20s, was arrested in Kajang this morning after police received a report on the incident.

“They are being remanded for a day to facilitate the investigation,” he told reporters at KLIA Terminal 1 today, adding that police also seized their car.

Hussein also said police identified six other vandalism cases – four in Sungai Buloh and two in Petaling Jaya – at fast-food premises such as KFC, McDonald’s, and Subway from May 28 to 30.

The four outlets in Sungai Buloh were vandalised with offensive words, and the police believe they were committed by the same individuals, he said

Hussein said police would open another investigation paper, after both suspects tested positive for drugs.

He advised the public not to express strong views or take matters into their own hands, to the extent of disrupting the peace and harmony in the country.
