Police found more than 40 skulls, dozens of bones and a fetus in a glass jar next to an altar in the den of suspected drug traffickers in Mexico City during a raid this week, authorities said on Sunday.
Four of the skulls were built into the altar in the central Tepito neighborhood, where police arrested 31 people on Tuesday on suspicion of drug cartel activity, the city government said in a statement. A judge ordered 27 of the suspects released.
A photo distributed by the Mexico City attorney general’s office showed skulls clustered around the altar, which had a cross behind it adorned with a horned wooden face mask.
To the right of the altar was a painted wall full of symbols that included a pyramid topped with a hand, celestial bodies and the head of a goat with a hexagram between its horns, according to photos of the room published by local media.
