According to UK police, offensive leaflets targeting Polish immigrants were distributed in Huntingdon, Cambridgeshire on Sunday, just two days after the so-called Brexit referendum results were announced. On the same day, suspected racist graffiti was daubed across the front entrance of the Polish Social and Cultural Association (POSK) in west London.
"We are shocked and deeply concerned by the recent incidents of xenophobic abuse directed against the Polish community and other UK residents of migrant heritage," the embassy said in a statement on its official Twitter.
"We call on all Polish nationals who fall victim of xenophobic abuse and on all witnesses to report such incidents to local authorities," the embassy said.
On Thursday, a nationwide referendum was held in the United Kingdom in which 51.9 percent of the voters said they were in favor of the country withdrawing from the European Union. Brexit campaigners have used the immigration issue as one of the main arguments to persuade people to vote for leaving the bloc.
