On Sunday, FC Seoul played their first home match of the K League season.

The ground was empty – one of many measures designed to prevent a Covid-19 outbreak.

So before the match, a company called Dalcom offered to fill some of the empty seats, and the club agreed.

In total, there were 30 mannequins – 25 of them female, and five of them male.

However, fans watching online noticed that some of the mannequins looked more like sex dolls – leading to the club apologising on Instagram and Facebook.

Club official Lee Ji-hoon said it didn’t do a background check on Dalcom, and didn’t realise their line of work.

But the club said that Dalcom insisted the dolls were merely “premium mannequins”, rather than anything more x-rated.

Mr Lee admitted he thought the dolls looked “very human” – but said it didn’t even enter his mind that they could be sex toys.
