Police are investigating after signs reading 'Leave the EU - No more Polish vermin' were posted through doors in shocking post-referendum racism.

Laminated cards were reportedly delivered to members of the Polish community in Huntingdon, Cambridgeshire.

They were also found on the road near St Peter's School at around 8.30am on Friday, with a translation on the back reading 'go home Polish scum.'

Teachers reportedly threw away the cards, but more were left on the path leading to the school by the end of the day.

Polish-language newspaper Nasze Strony wrote that Poles who are already scared about the effects of the Brexit vote did not expect to be harassed after the results.

Nasze Strony reporter Adam Andrzejko said it was a 'very sad example' of the response to the EU referendum result.

A Facebook user wrote that yesterday morning one of the cards had been placed on her mother's doorstep held down with stones so that it didn't blow away.

She wrote that she was 'absolutely disgusted', and continued: 'Whatever anybody's view in this referendum there is no reason for vile things like this.'

Another Facebook user reported that her husband had found one of the cards 'down an alley way, next to people who are Polish.'
