SINGAPORE - There has been no evidence to support an allegation that a staff member "looted" tickets to Ed Sheeran's concerts at the Singapore Indoor Stadium, said a Singapore Sports Hub spokesman on Sunday (May 14).

The statement comes a day after reports of a Carousell user claiming that a Sports Hub staff member bought 220 tickets to Sheeran's sold-out concerts in November to resell them. The allegation prompted an investigation by the Sports Hub.

"We have reviewed the transactions performed. There were no suspicious transactions, and tickets were purchased within the respective transaction limits," said the Sports Hub's senior director for corporate communications and stakeholder management Chin Sau Ho.

The spokesman said while the Sports Hub treats such allegations "seriously", it has "confidence in the integrity of (its) staff and systems".

He added that "no resellers have been authorised to sell tickets for this show", urging patrons to purchase through official and authorised channels.

On Saturday, it was reported that a 24-year-old student going by the name Aida Aretha on Facebook posted screenshots of a conversation on online marketplace Carousell, where another user was selling Category 1 tickets at $1,100 a pair.

The tickets, released by ticketing agency Sports Hub Tix, originally cost $248 each.

In the screenshots, the seller claimed his friend was in the Sports Hub management and bought 220 tickets - 100 tickets for the Nov 11 concert, and 120 for the Nov 12 concert.

The seller said he had 24 tickets and was keeping two for himself.

The Sports Hub said in an earlier report that it does not allow in-house bulk buys by staff.

Concert organisers here have also previously voided tickets that were resold online at inflated prices.
