"We have arrested a person who produced fake T-shirts and recovered stocks from several retail outlets," Senanayake told AFP. "Investigations are underway."
The ICC said local manufacturers were in the process of turning out "large quantities" of fake team shirts belonging to the 12 countries competing in the World Twenty20 tournament, which opened in Sri Lanka Tuesday and ends on October 7.
The governing body's legal chief Iain Higgins said in a statement that counterfeit goods were a "menace" to all their global events.
"The ICC is determined to protect not only the valuable commercial rights of its partners, but also the interests of the public who may find themselves unwittingly purchasing inferior counterfeit products," he said.Sri Lanka has a successful $4.1-billion garment manufacturing industry which produces clothing for some of the world's top international brands.
