(CNN) -- Police were investigating after a young Polish man streamed his suicide live over an Internet chat site, reports said Tuesday.
Prosecutors in the southeast Poland town of Zargorz said the man logged onto Web site Interia.pl on Sunday before hanging himself in front of a camera, Agence France-Presse news agency said.
"One Internet user witnessing the act immediately alerted police, but officers who arrived on the scene found the man's corpse hanging from a pipe," local prosecutor Wieslaw Klaczak told AFP.
Another official, Tadeusz Halas, said the man had earlier been drinking with friends to celebrate his 27th birthday, Reuters.com reported.
"He told them he had prepared a surprise for his birthday but they said he seemed very strange and depressed," Halas said.
He said the man's parents had been sleeping in another room of the apartment at the time of his death.
