According to the Mirror, three women—one reportedly a girlfriend of a prisoner—arrived at the prison early Thursday morning, around 3 o'clock. The women reportedly asked to be let inside to "chat and drink," eventually leading the three prison guards to the staff's sleeping quarters.
"They served them cheap whiskey with some substance to knock them out, then unlocked the central gate which accesses the internal cells," Police Chief Angelina de Andrade Ferreira told a news conference. "Whoever wanted to escape left by the front door."
Police found a bag of lingerie and law enforcement-themed dominatrix outfits, believed to have been worn by the women who came to the prison on Thursday morning. Authorities believe the jailbreak was planned by 18-year-old Bruno Amorim, serving time for attempted murder, robbery, and firearms possession.
The inmates made off with rifles, shotguns, revolvers, and some ammunition, Ferreira said. The three wardens have been arrested and will be charged with "facilitating a jailbreak" and "culpable embezzlement."
Eight of the 28 escaped inmates have been returned to prison.
