The FBI confirmed Wednesday that its agents were at multiple locations in Laredo "conducting law enforcement activity."

While it was not immediately clear what the activity was, Special Agent Michelle Lee confirmed to KENS 5 that the agency was "lawfully present" at multiple locations, including Laredo City Hall, Laredo Public Works Office, Laredo Utilities and Webb County offices.

Lee said that the buildings were not being evacuated and that there was no public safety threat at any location.

"The buildings were not being evacuated, as some concerned citizens may have reported. Rather, employees working in certain areas were asked to leave," Lee said in a statement.

KENS 5 has also confirmed with the FBI that the agency has raided the offices of Dannenbaum Engineering in four cities including San Antonio, Laredo, McAllen, and Houston.

No word yet on whether those raids are connected.

Dannenbaum engineering issued a statement following the raids:

"Dannenbaum Engineering, one of the state's premier firms for infrastructure planning and design, is cooperating with federal authorities regarding government requests for information. Company management is investigating the basis of the government requests. We are uncertain whether the inquiry is focused on the company's activities or those of its business competitors. We intend to comment further when appropriate."

James Dannenbaum is the president and CEO of Dannenbaum Engineering and sits on the Alamo Endowment Board.

The FBI confirmed to KENS 5 that they anticipated all of these offices to be closed all day Wednesday and expected to have agents on scene for most of the day.

"If you are planning on visiting any of these buildings today, to avoid any inconvenience, we recommend members of the public call to ensure they are open for business," Lee said.

Security guards and DPS troopers were seen turning away people all day in Laredo while agents went in and out of the buildings there.

Statement from The FBI:

"The FBI is lawfully present at the Commissioner’s Court Building. The only area that is being affected is Precinct 4. No other offices in this building have been affected. While we cannot discuss the nature of the work that they are doing, there is no public safety threat at the locations where they are present."

Laredo Mayor Pete Saenz told KENS 5 he stands for transparency and will cooperate with investigators.

"The FBI has raided several city and county government buildings in Laredo. As of 1:30 p.m. on 4/26/17, I have no further information on the FBI's activity or investigation. I stand for transparency and will continue to fully cooperate and support this investigation. When the FBI comments further, I will update our community."
