Police have arrested a man for using forged documents and making false crime reports, after he allegedly fabricated an email from the Kai Tak Sports Park and separately claimed he was the victim of a blackmail case.

Officers alleged that the man released a press statement earlier this month claiming that his application to host an international football event -- featuring FC Barcelona -- at the new stadium was rejected, and included what he claimed was an email from the park.

Kai Tak Sports Park said it never received any application documents about the proposed match.

Officers said the suspect also filed a false police report claiming that a journalist covering the story blackmailed him for HK$10 million via an email.

Sun Yi-ki, a chief inspector with the force, said officers believe both emails were forged by the suspect.

"Police do not rule out that the suspect may have been overly optimistic about his ability to organise international events. When his plan failed due to inexperience and poor management, he tried to shift the responsibility by misleading the media and forging emails that falsely claimed Kai Tak Sports Park had rejected his venue application," Sun said.

Kai Tak Sports Park said it is willing to cooperate with the police probe and will continue to handle all leasing applications in a professional manner.
