The MailOnline quoting BBC Swahili reported that the operation by Nigerian police was launched after they were tipped off by local who suspected something horrific was taking place inside the kitchen.
The report further added that human heads dripping with blood in plastic bags were discovered following the operation by police.
The restaurant was located in the south-eastern province of Anambra where a local priest who ate the restaurant was alarmed at the price of meals there, let alone where the meat came from.
The priest said he was alarmed after receiving a bill of 700 Naira – around £2.20 – when the daily wage for tens of millions of Nigerians is approximately 60p.
“The attendant noticed my reaction and told me it was the small piece of meat I had eaten that made the bill scale that high,” the priest added.
He said “I did not know I had been served with human meat, and that it was that expensive.”
At least ten people were arrested by police and an arsenal of weapons including grenades were discovered and confiscated following the raid.
One resident said, “I am not surprised at the shocking revelation… Every time I went to the market, I observed strange activities going on in the hotel”
“People who were never cleanly dressed and who looked a bit strange made their way in and out of the hotel, making me very suspicious of their activities,” the resident added.
