(CNN) Malaysian police say the Islamic State has carried out its first successful attack in the country.

Inspector-General of Police Khalid Abu Bakar told CNN that a grenade attack on June 28 at a nightspot near Kuala Lumpur, the country's capital, was carried out on the orders of a Malaysian Islamic State fighter in Syria, Muhammad Wanndy Mohamed Jedi.

While there were no fatalities in the attack, eight people were injured. Most of the people at the nightclub, called Movida, were there to watch the Spain-Italy Euro 2016 match.

"One of the policemen was picked up for harboring ISIS elements, while the other was arrested for involvement in robberies to collect funds for ISIS," he told CNN.
