A man who was featured on the El Paso County Sheriff's Office "Manhunt Monday" was arrested in Juarez on Sunday, said a spokesman for the office.
Javier Ivan Madrid-Lara was one of three people arrested by Mexican federal police, who are believed to be members of a Juarez gang.
Investigators say Madrid-Lara and the other men had several high powered, fully automatic rifles and ammunition.
U.S. Authorities say Madrid-Lara was using another name when he was arrested.
He was wanted for aggravated sexual assault and making a terrorist threat.
