Police investigating a report of racial abuse during Millwall’s Championship game against Swansea City have arrested a man.

The match on Tuesday, 13 October was paused during the second half while referee Edward Duckworth had lengthy discussions with both sets of coaches.

An announcement was made on the stadium speakers at The Den warning against any form of racism and that police were working to identify any offenders using CCTV.

Swansea head coach Vitor Matos later alleged the comments were aimed at South Korea winger Eom Jisung.

“A 51-year-old man was arrested on Wednesday, 14 October at an address in Kent on suspicion of racially aggravated intentional harassment, alarm or distress,” the Metropolitan Police said in a statement.

“He was taken to a south London police station and he has been released on bail until a date in mid-January pending further enquiries.

“The Metropolitan Police Service takes all reports of discriminatory abuse seriously and will work with football clubs and relevant stakeholders to investigate allegations of this nature.”

Eom was among the Swansea substitutes warming up alongside the pitch when the game was brought to a halt during the second half.

“The referee followed the protocol for these sort of situations, they did the right thing. Millwall also did the right thing to get the protocol moving on,” said Matos after the match.

“We all know there is no space for this. This kind of situation should not happen.

“When they do happen we are here to stand with the player, in this case it is our player.”

The incident marred what was otherwise an evening of celebration for the Swans, as Ronald’s late strike sealed a 1-0 win for the league leaders.

Millwall stated they were aware of an alleged, individual incident of discriminatory abuse towards a Swansea player and was supporting the police investigation.

“The club operates a zero-tolerance policy towards any form of discriminatory abuse,” it added.

“Any individual found to have engaged in such behaviour will face the strongest possible action.”

However Millwall manager Alex Neil has been criticised by anti-racism campaign group Kick It Out after appearing to question the decision to halt the game.

“I understand there’s been an incident. It’s not something I’m going to get involved in. That’ll be for the authorities to deal with,” Neil told BBC Radio London.

“But the fact that it stops the game for 15 minutes, I just don’t see the point. It needs to get dealt with, absolutely, but stopping the game doesn’t deal with anything. All it does is kill the momentum.”

Victory kept Swansea two points clear at the top of the Championship, with the Welsh club putting together their best start to a season in a century.

Matos said he was saddened by the alleged abuse aimed at Eom, but added the squad will rally around their team-mate.

“He is a smart kid, he is not happy with the situation but he knows we will stay with him and follow the situation as long as we can,” added Matos.

“Millwall did the right thing by announcing there is no place for this sort of thing.

“I’m happy with how it was handled, but really sad that it happened. Now it is about evaluating the situation and we’ll see what happens.”
