Police in Peru have recaptured a man who escaped from prison by swapping places with his twin brother.

The arrest of Alexander Delgado Herrera marks the end of a year-long manhunt.

Herrera had been serving a 16-year sentence for child sexual abuse and robbery when his brother Giancarlo came to visit him in prison in January 2017.

Police said he drugged his brother, swapped his clothes and walked free.

Amid the confusion, Ciancarlo was arrested for aiding his brother’s escape, but the charges were later dropped.

Police had offered a reward of 20,000 Peruvian Sol (€4,900) for information on his whereabouts.

Alexander Herrera was arrested on Monday after an extensive operation in the port of Callao, west of the capital Lima.

The Interior Ministry said: "Today there was the recapture of a rapist who on January 10, 2017 left Piedras Gordas [prison] being supplanted by his brother.

"This relative was detained instead of him, but today Delgado Herrera has already been arrested."

Local media reported that he had escaped because he wanted to see his mother.

He is now expected to be moved to a maximum security prison to serve the remainder of his sentence.
