The Federal Prosecutor arrested 2 suspected spies. A man was caught in Spain. A woman was arrested in North Rhine-Westphalia. Both worked for a Russian intelligence service.
They probably watched a business man in Germany. This man sends drones and building parts to Ukraine. The spies gathered information on the internet. They also secretly filmed his work place and his home.
First, the man watched the target person. Later, the woman took over this job. Investigators think: The spies wanted to prepare more actions. At the same time, there were drone attacks in Lviv in Ukraine.
