(CNN) -- A U.S. Customs and Border Protection Officer was behind bars Monday after being arrested for allegedly helping drug traffickers move their product into the United States. The arrest of Jose Luis Zavala, 38, a CBP officer in Brownsville, Texas, follows an investigation by Homeland Security Investigations and Department of Homeland Security Office of Inspector General, the CBP said. Zavala has been with the CBP for seven years and is now on administrative leave, the agency said. According to a criminal complaint, Zavala came to the attention of investigators on November 19, when a van carrying about 3,000 pounds of marijuana tried to enter the United States at the Gateway International Bridge in Brownsville.
