Not exactly. This is the pig's head story as reported by the Guardian.
Arday confirmed in an interview with the Guardian that the “mutilated animals sent to his family home” mentioned in the open letter was a severed pig’s head, delivered in a large cardboard box to his parents’ home address in south London. He claimed to have intercepted the package and immediately thrown it away, only telling the police several months later.
In a subsequent interview he claimed the police investigated, checking with butchers in south London if they had sold a pig, eventually finding one that had sold a “whole hog” on the morning the head was left outside the family home.
When the Guardian checked those details with the local butchers Arday named, they said no police officer had come in to ask them about a pig. When asked if they were sure, the butcher said “that’s the kind of thing we’d remember”.
When the details Arday gave about the pig’s head investigation were checked by London’s Metropolitan police, the Guardian was told they were “categorically” incorrect and no investigation had taken place.
