Two people have been arrested after a Polish shopkeeper with a heart condition collapsed during a race hate crime.
A 53-year-old man and a 39-year-old woman are being questioned by police following an alleged incident at Bramley Shopping Centre in Leeds on Tuesday morning.
The 47-year-old victim, who has a pre-existing heart condition, is recovering at home after being taken to hospital for treatment.
West Yorkshire Police said the suspects were arrested on Friday morning at an address in Armley, Leeds, as part of an investigation into the racially-aggravated public order offence at the victim's shop.
Chief Superintendent Paul Money said: "We treat all reports of hate incidents very seriously and want victims to come forward with confidence, either directly to the police or through our partner agencies, and be fully reassured that their complaints will receive the appropriate response.
"We are very conscious of the increased focus on incidents of this nature at this time and hope that people will be reassured to see that we have acted promptly to progress this investigation.
"Officers from the local neighbourhood policing team will be continuing to provide additional reassurance in the area and we will continue to respond appropriately to any other reports we may receive from anywhere else in the district."
On Thursday, the force said it had not seen an increase in hate incidents reported in West Yorkshire since the EU referendum result, and it reassured the public that such incidents will not be tolerated.
Temporary Assistant Chief Constable Angela Williams said: "While we have not seen a rise in hate incidents reported to West Yorkshire Police since last week's referendum result, we understand the heightened concern in some communities and are aware of the increase in reports nationally to various agencies.
"West Yorkshire is home to richly diverse communities and I want to be clear that there is no excuse for hatred and intolerance on the grounds of race, faith, disability, sexual orientation or gender."

The victim, Marek Petzold, was outside his shop, the Koala Delicatessen, when he was verbally abused.
His wife, Wioletta Petzold, told how she was scared for her husband after he collapsed following the attack.
Mrs Petzold, 46, said: "It was a big shock. He was outside the shop when some people shouted at him 'leave this country' and 'go to your own country' and some swearing, that I don't want to repeat, and things like 'why are you still here?'.
"When he came back into the shop, he lost consciousness and I was scared about him because he was in a bad condition with his heart. He stopped breathing and I called an ambulance. He went to the hospital and everything is alright with him now, everything is okay."
Mrs Petzold added: "I think some people maybe they think wrong about the referendum, that Polish and Slovakian and Hungarian people must leave this country."
But the shopworker said they had received messages of support from across the country.
She said: "After this we have felt a lot of support from Bramley. A lot of people came to the shop and said they were sorry for the people, they brought us a lot of flowers, a lot of cards with the words 'sorry about this', we even got some cards from London. They said 'we are friends with you', that's really polite, really kind.
"Before this, we were made to feel very welcome, I didn't even imagine that something like this could happen."
