A suspected drug gang leader wanted in the United States has been arrested and her son killed in Honduras.

When two special units were deployed in a forest in the municipality of Limón on the Caribbean coast, three other Hondurans were arrested, the Central American country's police said on Sunday.

A relative of the arrested Herlinda Bobadilla was killed when he fired at the officers - according to media reports it was her son Tito Montes.

Another son of the 61-year-old, Juan Montes, was reportedly at large.

In the cases of all three people, the US government had offered a reward of up to five million dollars (4.8 million euros) each for information leading to their arrest.

The trio led the Montes Bobadilla gang, which is said to be involved in smuggling cocaine from South America to the United States, as well as violence and corruption.

A third son was extradited to the United States in 2017 and sentenced to 37 years in prison.

Since left-wing President Xiomara Castro took office in January, her predecessor Juan Orlando Hernández and former Honduran police chief Juan Bonilla, aka “El Tigre” (The Tiger), have been extradited to the United States for alleged involvement in drug trafficking.
