A grief-stricken relative was left horrified after she went to bid farewell to her elderly uncle - only to discover another man wearing the suit she had chosen for him lying inside the casket.

To add insult to injury, traumatised niece Amentha Hunt then claimed funeral home workers asked for 'proof' the wrong body was lying inside the coffin.

The unfortunate error has led the family of Otis Adkinson, 80, to launch a lawsuit against Harrison-Ross Mortuary, in Los Angeles, California.

Speaking to KCAL News, Ms Hunt, from Compton, said the incident had left her family traumatised.

'It shouldn't have happened. I didn't make arrangements there to see the wrong body.
