Prosecutors allege that the motorcycle club members tried to kill four people and seriously injured others last year at a restaurant on the outskirts of Portugal's capital, Lisbon. The restaurant was destroyed in the Hells Angels attack.
At the time of the restaurant attack, the Hell Angels was involved in a war for control of illicit guns and drug trade, according to authorities.
