Cabinet minister Patali Champika Ranawaka and JHU general secretary urged the government to protect the former military general, Jagath Jayasuriya who has been accused of war crimes.
"The government should represent him and deny allegations," Mr Champika said at a press conference.
"Former president Mahinda Rajapaksa released around 12,000 LTTE cadres without proper investigations. If plans are made to hunt down Sri Lanka's tri-forces personnel we have to keep aside the good governance policies and press for proper investigations on released LTTE cadres," he added.
Mr Jayasuriya this week fled Brazil where he was posted as ambassador after human rights groups filed lawsuits in Brazil, Colombia, Peru and Chile over his role in the military in 2009.
