Supermarket says sorry for 'dark panther' costume

A British supermarket chain has apologised for incorrectly marketing a Black Panther costume as "dark panther".

A savvy shopper spotted the "dark panther" costume for sale on Tesco's website under the title ""Marvel Avengers Dark Panther Fancy Dress Costume".

She asked the UK supermarket to "please explain" why the phrase "dark panther" was used when there was no such character in the movie.

They wrote: "There is no dark panther in the kingdom of Wikanda ... why have you done this?"

In a statement, NME.com reported a Tesco spokesperson as saying: "This was a mistake and we are extremely sorry for any offence caused.

"We are correcting the description of this product on our website and are reviewing our processes to ensure this doesn't happen again."

Black Panther has broken records since its release, and could earn a spot on the highest grossing films ever made.
