Mexico City: The Mexican army made a rare public apology over a scandal in which two soldiers and a policewoman tortured a terrified woman in a video that went viral.
It is just the latest allegation of abuse committed by security forces in Mexico, who are often accused of violent acts against civilians, including murder.
General Salvador Cienfuegos, the defence minister, read out the apology before 26,000 soldiers assembled at a military base in Mexico City yesterday.
"In the name of all of us who make up this great national institution, I offer my heartfelt apology to all in society wronged by this impermissible event," Cienfuegos said.
In the video, which went viral on social media this week, a barefoot woman is seen crying and screaming on the floor as a female soldier puts the muzzle of an assault rifle to her head.
A federal policewoman is then seen handcuffing the woman and proceeding to tightly wrap a plastic bag around her head while one of the officials demands threateningly: "Are you going to talk?"
The incident is reported to have taken place in February 2015 in the town of Ajuchitlan del Progreso, in the southern state of Guerrero.
The defence ministry says it only learned of the video in December.
The male army captain and the female soldier seen in the video were arrested in January and charged with disobeying orders.
Mexican authorities are investigating a policewoman to determine if she was the one in the footage.
"It's necessary to publicly express our outrage over the regrettable events that occurred nearly 14 months ago," Cienfuegos said.
"Bad members of our institution besmirch the honourable behaviour of thousands of women and men in military uniform," he added.
"Although isolated, (such incidents) damage in a major way our image and the prestige we have worthily earned."
Cienfuegos told the soldiers they would continue to be on the frontlines of Mexico's war against drug cartels.
But he stressed: "We must not, nor cannot, confront illegality with more illegality. Crime is contained with the law in hand."
Federal prosecutors have been investigating the case officially since January 7 and they plan to try the three troops in a civilian court.
