( CNN ) -- The Mexican Federal Police captured eight people involved in a daylight shootout that paralyzed three sections of Ciudad Juarez , Mexico , Wednesday afternoon , authorities say . Among those arrested were five cartel members with ties to the Sinaloa cartel who admitted to being involved in the kidnapping of a groom and three others at a wedding in Juarez on May 7 , Municipal Police spokesman Jacinto Seguro told CNN . The four victims from the wedding were found dead in the back of a pickup truck days later . Some have speculated that the groom , a U.S. citizen whose family owns a transporting company in New Mexico , had ties to the Juarez cartel . When the bodies of the victims were found , they showed signs of torture . The victims also had pig faces drawn on their foreheads , a symbol used by the Sinaloa cartel to describe their rivals from the Juarez cartel . Federal police said the other three of the eight people detained had ties to the Aztecas , a local gang of drug dealers in Juarez that acts as the enforcing arm for the Juarez cartel in the city . With them was a man from El Paso , Texas , who had been kidnapped and held for 15 days , Seguro said . The sequestered man , 54 , identified only by his alias `` El Pistolita '' had ties to a cartel , Seguro said . The eight men were captured Wednesday in two separate events that took place between 2 p.m. and 3 p.m. , Seguro said . Police identified the detained Sinaloa cartel hit men as Ricardo Esteban Rubalcaba Reyes , 24 , alias `` El Guawis '' ; Jose Alfredo Monreal Escajeda , 37 , alias `` El Primo '' ; Porfirio Rubio Valle , 48 , alias `` El Pilo '' ; Jesus Emilio Gil Acosta , 40 , alias `` El Milo '' ; and Cecilio Torres Adriano , 43 , alias `` El Cilo . '' Among the men detained with Aztecas/Juarez cartel connections were Tomas Antonio Duarte Amaya , 33 , alias `` El Tony '' ; and Jesus Alfredo Lopez Cruz , 30 , alias `` El Chuy , '' police said . A third member of the Juarez cartel , who was only identified by his first name `` Jesus , '' is 17 . Mexican law prohibits the release of the identity of minors . Pictures from arrests showed an arsenal of weapons and ammunition seized during the captures . The three from the Juarez cartel were detained while riding in a stolen green Ford Windstar which they used in a separate attack on a residence in Juarez , police said . Mexican federal police are calling the captures the most significant arrests since they took over security from the Mexican military one month ago .
