By Sarah Hannan Seven Chinese nationals illegally employed at the Aruwakkalu solid waste management facility were arrested on Friday (18), raising fears that more such unauthorised foreigners maybe working at the site. The Ministry of Megapolis and Western Development said that it was not aware if there were employees at the site without valid visas as a Chinese contractor was heading the project. The Puttalam Division Community Police unit arrested the Chinese nationals and handed them over to the Wanathawilluwa Police station for further questioning. Ministry of Megapolis and Western Development Secretary Nihal Rupasinghe, when contacted by The Sunday Morning, said that the Ministry was not aware of the arrests. “A Chinese contractor is heading the project work and there are Chinese nationals who are employed there. For all Chinese nationals who are recruited in an official capacity, we issue work visas. The Ministry is unaware of any illegal Chinese immigrants that were arrested from the site on Friday,” Rupasinghe said yesterday. When contacted by The Sunday Morning, the Wanathawilluwa Police said that they were investigating to see if more Chinese nationals were employed at the site without valid work visas. An officer attached to the Wanathawilluwa Police said that the seven suspects arrested on Friday were produced before a Magistrate last afternoon.
