Three German nationals have been arrested in Pakistan's Peshawar city for alleged illegal activities, police said.
Police officer Mian Saeed said the three Germans were being questioned for their illegal stay and running an office in Peshawar, the capital of northwest Khyber Pakhtunkhwa province, Xinhua reported.
Police raided a house Saturday in the University Town area and took the three Germans into custody, Saeed said.
The Germans had been running an office but failed to show any documents related to permission from the government.
A police officer said the Germans told authorities that they opened the office for "coordination" between the two countries. They also said they were monitoring "German-funded development projects".
There has been no comment from the German embassy in Islamabad.
