The second semi-final in Cardiff between Sri Lanka and India was played out among security concerns after pitch invasions and fracas outside the ground.
Protesters invaded the pitch during both innings of the match with several running into the Sri Lankan players and one even laying hands on Kusal Perera, who backpedalled and escaped his grasp.
Security officials stationed inside the ground broke up the incidents but the Sri Lankan team's departure from the ground was delayed until their exit could be secured.
The Sri Lankan High Commission in the UK had raised fears about such incidents and had written to Scotland Yard requesting special security measures be put in place for the Sri Lankan team.
The events raised questions over the security of the Champions Trophy, which is provided by G4S, the same firm who were heavily criticized over their handling of security for the London Olympics.
The firm's chief executive, Nick Buckles, resigned in May.
Experts state that not only does this raise questions regarding the security provided for the Champions Trophy, but also raises questions regarding British Intelligence services.
The protests continued after the match had finished, and a fight broke out outside the ground between protesters and supporters which was subsequently broken up by the South Wales Police.
However when inquired by the Secretary to the Ministry of External Affairs Karunathilleke Amunugama regarding the Sri Lankan governments response to the Cardiff incident he noted that a report has already been requested of the Sri Lankan High Commission in the UK.
Meanwhile UNP MP Dayasiri Jayasekara states that the lives of Sri Lankan’s residing in the UK have come under threat following clashes which erupted between pro-LTTE supporters & Sri Lankan nationals during a recent match which was played between Australia & Sri Lanka at the Oval grounds.
