Tharanga, who scored two runs off 20 deliveries in the match at Mumbai´s Wankhede Stadium, was called in after investigators quizzed chief selector Aravinda de Silva for almost six hours on Tuesday. "Based on the statement given by Aravinda de Silva today, we have chose to summon a player from the 2011 squad, Upul Tharanga, tomorrow to record his statement", Superintendent Jagath Fonseka told reporters.
Tharanga, who is to be questioned Wednesday, was Sri Lanka's opener at the finals.
Close on the heels of former Sri Lanka sports minister Mahindananda Aluthgamage claiming that the Sri Lanka cricket team "sold" the World Cup 2011 final to ensure victory for India, a probe has been reportedly ordered into the allegations.
"A criminal investigation has begun", said KDS Ruwanchandra, the secretary to the sports ministry, as quoted by news agency AFP.
De Silva, who was the man of the match in Sri Lanka's 1996 World Cup triumph, was the first to be interviewed by the newly formed anti-corruption unit (sports).
Reportedly, it is being handled by the (police) independent Special Investigation Unit on sports-related offences.
Earlier, he reiterated the match was "sold", however, he did not name any player involved.
Batting first, Sri Lanka had scored 274 for six after Mahela Jayawardene smashed an unbeaten century.
India won the final by six wickets.
But India turned the game dramatically, thanks in part to poor fielding and bowling by Sri Lanka, who were led by Kumar Sangakkara. They appeared in a commanding position when Indian superstar Sachin Tendulkar was out for 18.
Last month, the Sri Lankan cricket board said the International Cricket Council was investigating three unnamed ex-players over corruption claims.
The consequences for any players found guilty are likely to be severe after match-fixing was made a criminal offense in Sri Lanka in November, introducing punishments of up to $555,000 and up to 10 years in jail for offenders.
