Inmates in one of Brazil's roughest prisons used explosives to destroy a wall and escape en masse into surrounding streets, prompting a frantic manhunt. Media footage of the brazen breakout on Saturday in the north-eastern city of Recife showed the blast ripping a hole in the main wall around the Frei Damiao de Bozanno facility.
After a cloud of dust and debris clears, a stream of men dressed in ordinary clothing can be seen dashing into the narrow streets before police arrive on the scene.
Pernambuco state justice authorities were quoted by Globo news site saying Sunday that 40 inmates escaped and that 36 had now been returned to custody, two killed, one hospitalised and one remained at large.
It took hours for officials to give figures, with Brazilian media initially reporting that as many as 100 prisoners could have got out.
