Authorities in Guatemala say they have arrested a former national police chief for his alleged involvement in the civil war-era disappearance of a union activist in 1984.
The 70-year-old Hector Bol de la Cruz was detained Thursday in El Progreso, a town about 85 miles (140 kilometers) east of the capital. He says he is innocent.
The former police chief is the fourth person detained in the case of missing activist Edgar Ferdnando Garcia. A judge sentenced two police officers to 40 years in prison last October. Another police officer has also been arrested.
Garcia was the 25-year-old husband of a congresswoman when he disappeared on Feb. 18, 1984.
Bol de la Cruz was national police chief from 1983 to 1985.
