SINGAPORE - Football fans heading to the Singapore Sports Hub on Tuesday (June 13) for the Singapore versus Argentina match should expect additional security measures in place that could "significantly increase" the time taken to enter the stadium.

In a media advisory on Monday (June 12), the Singapore Sports Hub advised spectators to arrive at the National Stadium at least one hour before kick-off and bring only what is needed to facilitate security checks.

Additional security personnel have been deployed and gates will open 1-1/2 hours before kick-off, at 6.30pm, it said.

"Despite more security personnel deployed for recent events, it has been observed that up to 75 per cent of patrons arrive in the last 30 minutes before an event starts, which resulted in many patrons clearing the security screening only after the event has commenced," said the advisory.

Over 20,000 fans are expected for the game, which will see the Singapore Lions take on the Argentinian team , as part of the Football Association of Singapore's 125th anniversary.

These security measures are in line with current licensing requirements for large-scale events, in response to the growing threat of terrorism in recent years.

Those without bags can use an "Express Lane", while bags exceeding 35cm by 20cm by 30cm and selfie sticks will not be allowed in the stadium.

"The Singapore Sports Hub seeks the public's understanding for the enhanced security measures, in the interest of everyone's safety," the advisory said.
