KK Mart branches in Bidor, Perak, and in Kuantan, Pahang, were attacked with petrol bombs last week, leading to the rulers of both states issuing strongly worded statements.

Tapah police chief Naim Asnawi said the seven witnesses called in as part of the police’s probe into the Bidor incident comprised KK Mart employees and members of the public, Sinar Harian reported.

Naim said that apart from the closed-circuit television (CCTV) footage from the premises, police have been unable to obtain any other evidence at the scene.

He added that police are patrolling the surrounding areas to prevent similar incidents.

The petrol bomb in Bidor failed to explode. The attack in Kuantan set several items on fire but it was immediately put out by the KK Mart workers on duty.

KK Mart has been mired in controversy since March 13 after socks with the word “Allah” were discovered at its Bandar Sunway outlet, sparking calls by Umno Youth for a national boycott of the chain.

KK Mart’s founder and a director have since been charged with intentionally wounding the religious feelings of Muslims by selling the socks, while three officers of the vendor, Xin Jian Chang Sdn Bhd, were charged with abetment. All claimed trial.
