LA JOYA – FBI agents are inside La Joya City Hall executing a search warrant.

The city administrator, Jacqueline Bazan, tells CHANNEL 5 NEWS they showed up unannounced around 8:15 a.m. Friday requesting access to the building.

About 15 federal agents are currently on the scene.

The agency didn’t offer many details, but they wanted to look through the paperwork at city hall.

City hall was shut down all operation, including the utilities department.

Some city employees were sent home, while others transferred to the police department next door to continue their duties.

The building's main phone line is not working at this hour as the investigation continues.

FBI Spokesperson Michelle Lee confirmed they are conducting “law enforcement activities”, but could not give more details, or confirm, if any arrests were made or expected.

Bazan tells us the FBI is expected to be at city hall throughout the day.

Agents have been seen walking in and out, but so far they have not pulled any items our from inside the building.

Bazan added agents did not request to speak to any employees.

“What I've been told is that they are looking to certain matters they will not disclose what matters those are, and what I've been told is this is a certain procedure that they need to do as part of their procedure internally,” said Bazan. “It is a standard search warrant, and I actually looked at it myself, and it does appear standard. It doesn't mention any details in particular as to what they will be reviewing.”

Even though the police department is adjacent to city hall, their operations have not been impacted.

Any residents needing to resolve any utility issues, should go to the police department for assistance.
