Mexico opens probe into death of woman shown pinned to ground by police

Mexican prosecutors have opened a homicide investigation into the death of a woman who was shown on video being pinned to the ground by a female police officer.

A video published by news site Noticaribe showed the woman squirming and crying out as she lay face down on a road with a policewoman kneeling on her back while male officers stood by.

The video then cut to show the unidentified woman's prone, handcuffed body lying on the road. Officers are later seen moving the limp, shoeless body into the back of a police truck.

Police were "probably" involved in her death, the attorney general's office of the state of Quintana Roo said in a statement following the woman's death on Saturday in the Caribbean beach resort of Tulum.

A spokeswoman for the attorney general's office said it was not clear why the woman had been detained and that the cause of her death was still under investigation. 

Three male officers and one female officer had so far been questioned.

The National Commission to Prevent and Eradicate Violence Against Women (CONAVIM) condemned the incident on Twitter and said those responsible must be held to account.

Also, Alejandro Encinas, deputy interior minister responsible for human rights, called the incident an act of "police abuse."

The case took prominence as it bore similarity to that of George Floyd, an African-American man whose death in May as a Minneapolis police officer knelt on his neck sparked racial justice protests in the United States and around the world.
