Poland has arrested a Chinese employee of Huawei and a Polish cyber business specialist on allegations of spying, state news agency PAP said on Friday, deepening the controversy over Western criticism of the Chinese telecoms equipment maker.
Poland security officials also searched the offices of Orange, one of the most subscribed telecommunication providers in Poland.
Following the U.S., Australia and New Zealand have also banned Huawei from supplying 5G networking equipment out of fear of a national security breach.

Huawei has come under global scrutiny lately.
"We are extremely grateful for his contributions to Huawei Canada during the past seven and a half years and I personally want to take this opportunity to thank him for the dedication and valuable support he has provided to me during the time we worked together".
Huawei said it "complies with all applicable laws and regulations in the countries where it operates, and we require every employee to abide by the laws and regulations in the countries where they are based". The company's chief financial officer, Meng Wanzhou, was detained in Canada in December and faces charges that she violated United States trade sanctions. A spokesperson for Orange Polska told NPR that the company was cooperating with authorities. She is out on bail in Canada awaiting extradition proceedings.
Huawei has been scrutinized for security concerns over its involvement in the development of 5G infrastructures.
