A pregnant woman begged for help after her hands were chopped off and put in a plastic bag.
The woman was thrown from a moving vehicle alongside two men, whose hands had also been chopped off.
The woman, believed to be 25, begged passersby for help, pleading: “Please, call my sister, please, friend, I will give you the phone number, please help me.”
The shocking incident took place on the road connecting the municipality of Silao in the central Mexican state of Guanajuato with the community of Trejo.
The so called Elite Group of the deadly Jalisco New Generation Cartel claimed responsibility for the attack.
The two men have also not been named but are reportedly aged 22 and 23.
They were all taken to hospital in a serious condition.
The bag containing the severed limbs was also accompanied with a message signed by the cartel which read: “This happened to me for being a rat (thief) and not respecting good, hard-working people.
“Anybody that does the same thing and continues to steal will suffer the same fate.”
A police investigation is ongoing and so far no arrests have been made.
The victims were unable to give statement due to their state of health, prosecutors told the newspaper El Universal.
