Puno: Peruvian police recently were left surprised when they recovered pre-Hispanic mummy from a food delivery cooler bag.

The cooler bag was recovered from the possession of a delivery man who came to the attention of the police for acting drunk at an archaeological site in Puno.

The delivery man left people shocked when he said he was sharing room with the bandaged mummy and considered it "a kind of spiritual girlfriend".

He had put the remains in the bag to show them off to his friends, the man was quoted as saying by BBC.

He explained that he kept "Juanita", as he had nicknamed the mummy, in a box in his room, next to the TV.

He added that it was owned by his father, without specifying how it had come into his father's possession.

Police told CNN that the mummified remains were found with three men who were drinking in a deserted park in the Peruvian city of Puno on Saturday afternoon.

“A 26-year-old man had a delivery bag labeled ‘Pedidos Ya.’ Inside they found a mummy,” senior agent Marco Antonio Ortega, who is a spokesperson for Puno region’s National Police, told CNN. Pedidos Ya is a Latin American food delivery app.

Experts told BBC the body was between 600 and 800 years old and that it was that of an adult male rather than a woman, as the man who was discovered with it had assumed.
