The bin bag of cats' heads found on a street near Manchester's famous Curry Mile could be "racially motivated", Manchester City Council has revealed this afternoon.

A spokesperson for Manchester City Council added that the area is known for its Indian restaurants, but said the council is not connecting the incident with any of the businesses in the locality.

The dumped body parts were discovered by a council cleaner responding to complaints about fly-tipping in the Ruhsolme area.

A single black bin bag containing the gruesome remains had been placed close to Warmer Street East and Basil Street.

The council today launched an urgent investigation and condemned the find as "an extreme example of animal cruelty" and branded it "sickening".

The chairman of the local Conservative Association, Stephen Woods, told the Manchester Evening News everyone was "flabbergasted" when they received the news.

The council said in a statement: "This is obviously an incredibly distressing and sickening incident which we are now looking into, but this is the first incident of its kind we have come across.

"At this stage we have no way of knowing how these animal parts came to be where they were discovered, but we will be contacting the RSPCA as this is clearly an extreme example of animal cruelty."
