A British-made radio antenna used in the World War II plot to kill Nazi leader Reinhard Heydrich has surfaced in a Czech village.

In April 1942, Jiri Potucek, a resistance fighter, parachuted into Czech territory by the Royal Air Force and hooked his radio up to the antenna to plan details of the attack, said Adolf Vondrka, who discovered the wires in the attic of a building on his fish farm in Lazne Bohdanec, 100 km (62 miles) east of Prague.

Potucek was among members of the Czechoslovak army-in-exile dropped into the country near the end of 1941. His broadcasts helped organize Operation Anthropoid, the attack on Heydrich. On May 27, 1942, paratroopers Jozef Gabcik and Jan Kubis attacked Heydrich's car with a hand grenade. The Nazi official died from his wounds a week later.
