Two San Bernardino County men were arrested last week for their roles in an alleged stalking, threats, and intimidation campaign targeting victims in Yorba Linda, California.

Xiang Li, aka "Lilinbo," 42, of Chino Hills, and Bowen Zhou, aka "Roger Zhou," 33, of Upland, were taken into custody this week pursuant to a criminal complaint filed in U.S. District Court in the Central District of California on June 17.

Beginning in March 2024, a victim identified in the complaint as "Victim 1," and her family member, identified in the complaint as "Victim 2," both of Yorba Linda, received threatening phone calls claiming they owed someone $150,000, suggesting they were not safe. On March 15, 2024, an individual drove to the Yorba Linda residence and left a threatening letter and a knife on the victim’s doorstep. Since then, the victims received numerous additional threatening calls and text messages.   

During one threatening phone call made to the victims, the caller stated, "You should know I know where your family lives, and we have a lot of gangsters in the L.A. area." On April 4, 2024, an individual fired six shots at the house while one victim was inside, according to the complaint.   

On June 3, 2025, the FBI executed search warrants related to the stalking investigation. During the search of LI’s residence, the FBI seized ammunition that matched the caliber of the ammunition used during the shooting incident, the phone used to send threatening text messages to Victims 1 and 2, and a phone used to contact Zhou around the time of the stalking incidents. During the search of Zhou’s residence, the FBI seized a firearm that matched the type of firearm that was likely used during the shooting incident, as well as the phone that was used to make the threatening calls and to contact Li around the time of the stalking incidents, according to the complaint.  

Both Li and Zhou had initial appearances before a federal magistrate and were remanded to federal custody. 

If convicted, Li and Zhou face a statutory maximum penalty of five years in federal prison. 

This investigation was conducted by the FBI and the Orange County Sheriff’s Department and is being prosecuted by Assistant U.S. Attorneys Joseph Guzman and Colin Scott.
