Federal agents arrested a manager of a Woodstock auto shop on Friday as part of a U.S. investigation that alleges drugs, including cocaine mixed with fentanyl, were being sold from the business. Genaro Bahena-Arellano, 50, listed as one of three managers of Woodstock Automotive Service LLC, was taken into custody in an operation that involved an FBI SWAT team, Drug Enforcement Administration agents and other federal and local law enforcement.
What happened at the Lake Avenue shop
According to a criminal complaint filed in the U.S. District Court for the Northern District of Illinois, the alleged distribution took place on July 17 at Woodstock Automotive Service, 725 Lake Avenue. The complaint, which had been under seal earlier this month before being signed by a federal judge, charges Bahena-Arellano with knowingly and intentionally distributing a controlled substance containing cocaine.
Investigators say the shop’s back room was used to sell the substance, which federal authorities allege contained fentanyl. The arrest drew a heavy response Friday morning after witnesses and social media posts showed a federal arrest warrant being executed and an FBI tactical team deployed near the intersection of Kimball Avenue and Lake Avenue. Residents were asked to avoid that area while officers carried out the operation.
Agencies and investigation
The case stems from a probe led by the DEA’s Rockford resident office in coordination with the Illinois State Police North Central Narcotics Task Force and the McHenry County Sheriff’s Office Narcotics Unit. The affidavit supporting the complaint says the investigation identified a drug-trafficking organisation responsible for transporting and distributing controlled substances across northern Illinois, and that investigators identified Bahena-Arellano as its leader.
According to the affidavit, the investigation began in July after the DEA received information from a confidential source. That source told agents they had been introduced to Bahena-Arellano earlier that month at Woodstock Automotive Service through a mutual acquaintance.
Woodstock Automotive Service appears in Illinois Secretary of State records with Bahena-Arellano listed as one of three managers of the LLC. The business address aligns with the location named in the court filing.
Federal court records allege the offence occurred at the Lake Avenue shop and that undercover information came from a confidential source introduced to the suspect there.
- Arrested: Genaro Bahena-Arellano, 50, of Carpentersville

The arrest Friday appears to be part of a broader federal effort in northern Illinois to disrupt organisations moving controlled substances across the region. The affidavit describes the target as a trafficking organisation operating in McHenry County and distributing drugs throughout northern Illinois.
Local residents said seeing tactical teams and federal agents at a downtown location was alarming. While authorities warned the public to steer clear of the immediate area near Kimball and Lake during the arrest, no further details were released locally about related arrests or additional charges at the time the complaint was filed.
Because the charges are filed in U.S. federal court, the matter will proceed through the federal judicial system. The complaint was signed by a federal judge after being filed under seal earlier in the month. Further proceedings, including any formal indictment, will be handled by the U.S. District Court for the Northern District of Illinois.
For Woodstock residents the case raises questions about activity at a long-standing local business and the extent to which federal investigations can involve visible, tactical operations in the city’s downtown. Authorities have not released further details about the scope of the organisation named in the affidavit, nor about any additional suspects connected to the investigation.
Local officials and the agencies involved did not provide immediate comment beyond the information contained in the court filing and agency statements identifying the ongoing investigation and the execution of federal warrants.
