Police officers exchanged racist WhatsApp messages, including an obscene joke about Auschwitz, a shocking report into bullying and harassment in the force reveals.

Sickening racist, sexist and homophobic messages were sent on the social media platform by serving officers, with one reported to have sent the message:

“Opened my balcony door and loads of flies flew into the front room. So I got the fly spray and turned my gaff into Auschwitz.”
