* Dinamo release Barboianu over match-fixing suspicion in local derby
* City rivals Steaua deny wrongdoing, consider legal action
BUCHAREST, May 7 (Reuters) - Midfielder Stefan Barboianu, hailed as a hero only months ago, has had his contract terminated by Dinamo Bucharest after the club accused him of "helping" bitter rivals Steaua win Romania's biggest soccer fixture on Sunday.
In October, Romanian media and fans praised Barboianu after the 27-year-old played against Steaua just hours after losing his infant son.
But only a few days after Steaua won 3-1 at the National Arena in their second clash this season, Dinamo showed Barboianu the door after blaming him for deliberately committing a foul in the penalty area 14 minutes from time to allow Nicolae Stanciu to score from the spot.
