Some queued for hours to catch the closing ceremony of the SEA Games at the National Stadium last night.
But, after going through security checks, an estimated 500 people were turned away at the stadium's gates and told they were not allowed in, despite holding valid tickets.
SEA Games organisers later put up a statement on their Facebook page apologising for the mistake.
"As a significant proportion of the spectators were at the gates just before the start of the ceremony, there was a need to adjust entry gates and seating arrangements to enable them to be seated as quickly as possible," the statement said.
"Consequently, some gates had to be closed for safety reasons. The organising committee apologises for the inconvenience caused and disappointment of those affected.
"We will offer a full refund to anyone who had purchased a ticket and was unable to be seated.
"In addition, you will receive the supporters' medallion."
A man who wanted to be known only as Abdul had bought tickets four tickets, but his group, which included his wife, son and daughter, were not allowed into the stadium.
"Even if we came late, we should still have a seat because we paid for it," said Abdul's 20-year-old daughter.
"And they allocated us by section, so there should still be seats."
Those affected can provide organisers their details at the Sport Singapore feedback page online, or by calling 1800-3441177 during office hours.
