WARSAW, Poland (AP) — Congolese authorities have released a Polish man who was sentenced there to life in prison on espionage charges, Poland’s top diplomat said Tuesday.

Mariusz Majewski is back in Europe, Foreign Minister Radek Sikorski said on X. Sikorski posted a brief video of himself apparently talking to Majewski over the phone to welcome him back. He didn’t say where exactly Majewski was.

The 52-year-old Majewski was detained in Congo in February and later faced a military court in the Central African nation, accused of spying. Last week, he received a life sentence in prison. No details were released as to where he was held.

The allegations against him said that he had “approached the front line with Mobondo militiamen,” moved along the front line without authorization and “took photos of sensitive and strategic places and secretly observed military activities.”
