Prison guards were surprised when they saw a white cat crossing the main gate of the prison, its body wrapped with tape. A closer look showed the feline also carried drills, an earphone, a memory card, batteries and a phone charger.

All 263 detainees in the prison of Arapiraca, a city of 215,000 people in the state of Alagoas, are considered suspect in the plot, which is being investigated by local police.
