(CNN) -- Mexican federal police have arrested a man who authorities say could have been involved in the March shooting deaths of three people with ties to the U.S. Consulate in Ciudad Juarez, Mexico, the country's public safety ministry said.
Jose Guadalupe Diaz Diaz, known as "El Zorro," is also suspected in the slaying of a federal police officer, the ministry said in a statement Thursday.
Authorities are investigating the 32-year-old's "likely participation in the killings of three people linked to the U.S. Consulate" in Juarez, the ministry said.
The statement did not specify how Diaz allegedly participated in the shootings. Thursday's statement from Mexican security officials described Diaz as a leader of the Aztecas gang, a street gang affiliated with the Juarez cartel.
Mexican authorities have arrested several others they accuse of being connected to alleged killing of three people with ties to the Juarez consulate.
The shootings occurred March 13 when consulate employee Lesley Enriquez and her husband, Arthur Redelfs, were gunned down as they left a birthday party in their white SUV.
