Facial recognition technology could be deployed at Kai Tak Sports Park and other venues to stop people sneaking in without tickets, Culture, Sports and Tourism Secretary Rosanna Law said on Tuesday.

Her comment follows a report by Wen Wei Po on Monday that two reporters managed to attend the park's opening ceremony last weekend despite not having tickets. The newspaper said the pair, and a man that helped them get inside, also managed to avoid security checks.

Law said police are investigating the alleged breach, but such a lapse wouldn't demonstrate any "large-scale loophole" in security measures.

She said there might be a need to use technology to stop people such as backstage staff from getting non-ticket holders into venues.

"The authorities need to check whether the person entering a place is the actual pass-holder. Say if you own the pass but you gave it to me, I shouldn't be allowed in," the minister said on an RTHK programme.

"Whether we can adopt real-name registration here, or, as some people suggested, use facial recognition, we can discuss these things with event organisers."

Law also said officials are hoping to bring non-local football teams to play at the sports park in the summer.

She added that the staging of the National Games in Hong Kong, Guangdong and Macau this November will provide a litmus test regarding the possibility of the region holding other major tournaments in the future.

"If we host the Games well, that would prove that the Greater Bay Area city cluster is very much capable of hosting major sporting tournaments. Would this be the Olympics, or, I've also heard others say, perhaps the Asian Games?", she said
