Authorities said the man's injuries were not life threatening, and as emergency workers took him out on a stretcher, the television engineer shouted, "Freedom!"
The stunt was apparently in protest over government budget cuts that had affected the man's family. Romania is mired in recession and the government recently cut public sector wages by one-quarter. The country's economy is expected to decline by 2 percent this year, after contracting by 7.1 percent in 2009. The cuts have angered many Romanians.
No one else was injured by the stunt.
Sobaru's dramatic gesture shocked lawmakers, some of whom wept. Boc looked startled and, along with other lawmakers, rushed over to Sobaru.
