Mexican authorities are reporting the arrest of a high-ranking member of the Gulf Cartel south of the border in Reynosa.
Mexico's National Ministry of Public Safety (SSP) reported that federal police arrested Gilberto Barragan-Balderas and two other men on Friday afternoon.
Residents used Twitter to report gunfire and a heavy police presence in a neighborhood on the city's westside.
SSP officials confirmed that Barragan-Balderas was captured along Gulf Cartel gunment Sergio Gutierrez-Castaon and Romeo Eduardo Mejia.
Mejia is the brother of Juan Reyes Mejia, a lead Gulf Cartel gunman known as "El R1."
Barragan-Balderas, who goes by the nicknames of "Heriberto" or "El Tocayo," was the reported Gulf Cartel plaza boss for Miguel Aleman, which is located across the Rio Grande from Roma, Texas.
Barragan-Balderas was on the U.S. Drug Enforcement Administration TMs (DEA) Most Wanted List where authorities were issuing a $5 million dollar reward for his capture.
All three men are expected to be flown to Mexico City where they will be prosecuted under organized crime charges.
SSP Director Ramon Eduardo Pequeo said the three were captured in an SUV with American license plates, weapons and ammunition.
"Among his responsibilities was to defend his plaza against the attacks of rivals, such as the Zetas in Tamaulipas," Pequeo said.
