"Many foreign labourers in the state have resorted to using force to intimidate their fellow countrymen.
"We will go all out to curb gangsterism involving a diversified mix of nationalities," he said after a community policing walkabout in the Pulau Tikus wet market.
Ayub said police would intensify their efforts to maintain public order in suburbs with a high concentration of foreign workers.
He was commenting on the parang attack by a Myanmar man on two locals in a fight between members of two secret societies outside a shoplot in Bandar Baru Air Itam on Friday night.
The two suffered serious slash wounds on the neck and hands and have been warded at the Penang Hospital.
Ayub said police rounded up 15 people, including the Myanmar man, shortly after the incident. - NST
