Reports of hate crimes and racial abuse have apparently rocketed since Britain voted to Leave the EU last Thursday.
Social media has been alive with stories of personal and group attacks on people with foreign backgrounds from within their own communities since the vote.
Here are some of the worst reports received in just the last four days...
Threatened to "be scared".
Polish PhD student Agata Brzezniak, 25, was on the bus on her way to university in Manchester just hours after the referendum result was announced, when a woman told her to be "scared" and to be "prepared to have to get a visa to be able to stay in her country".
Brzezniak said: "The vicious smile and the way she looked at me brought me to tears. I always thought I would be able to stand up for myself and respond to discrimination but this situation left me feeling scared, sad and hopeless. I got off the bus and decided to walk the rest of the way to university.
"I had never received any racist or discriminatory comments before the referendum. Sadly, I think the result of the referendum has almost 'empowered' the people who already had racist views to openly express them."
Being stared down on a train.
Graduate Natasha Bandlish, 21, from Dulwich, south-east London, was "flabbergasted" after a group of construction workers stared at her on the train while shouting about British independence.
She said: "They all looked at me and laughed while jeering and talking about how that day would be known as British Independence Day, and that next year it would be a bank holiday. One of them shouted it out and made direct eye contact with me and laughed."
She added: "I was just flabbergasted... It's such a backward attitude to have."
Name-calling and being told to "go home".
Kimberley Roberts, 31, originally from Chester, who works as a nanny in London, was called a "Chink" and told she would have to "go back home soon" when travelling on the Tube over the weekend.
In her words: "I felt hurt and confused at first. I wasn't sure why he was saying this to me. I'm English. My parents are English and my grandparents are English. All born and raised in this country.
"When I got off the Tube I felt sick and anxious. I was concerned as to how many more people he had spoken to like this."
Attacked at home.
It's one thing to face spontaneous abuse when out in public, where bystanders could step in if needed. But it's another matter when attackers seek out their victims to taunt them in their own homes - and especially if it's their own neighbours.
A German woman who moved to the UK with her husband in 1973 told LBC she was "frightened" after suffering a series of xenophobic attacks in the wake of last week's vote.
Crying on the phone, she said: "I'm so scared now. I've got dog turd thrown at my door. I haven't been out of the house for three days. My neighbours told me they don't want me living in this road. I don't know what is going to happen next."
