Mexico arrests retired general and 3 other Army members in case of 43 missing students

Mexican authorities have arrested a retired general and three other members of the army for their alleged connection to the disappearance of 43 students in southern Mexico in 2014, the government announced Thursday.

Assistant Public Safety Secretary Ricardo Mejia said that among those arrested was the former officer who commanded the army base in the Guerrero state city of Iguala in September 2014, when the students from a radical teacher's college were abducted.

Mejía said a fourth arrest was expected soon, and later a government official with knowledge of the case who spoke on condition of anonymity to discuss the matter confirmed that another member of the army had been arrested.
