FBI agents made an arrest at an Alhambra apartment Thursday morning and searched the residence.
Agents arrived at an apartment on the 300 block of 4th Street around 7:45 a.m., according to neighbors. They searched items and vehicles in a garage at the complex. Agents said they obtained a search warrant but declined to comment further on the investigation.
A neighbor who only wanted to be identified as Simon was caught off guard by the FBI presence. "I was just surprised that they showed up in unmarked cars this morning, about 8-10 FBI agents," Simon said, adding he did not have any personal relationship with his neighbors but saw them from time to time.
Another neighbor who wished to remain anonymous was also surprised. "The FBI came in pretty loud," the neighbor said. "They said they had been watching them for a while."
FBI informed local law enforcement of the operation but did not ask for assistance, said Sgt. Jerry Johnson of the Alhambra Police Department.
CORRECTION: An earlier version of this article stated that local enforcement was not notified of the operation. We regret this error.
