PHILADELPHIA (CBS) -- The FBI carried out investigations Friday, spanning across several locations throughout Philadelphia.
FBI agents seized dozens of cartons of files and computers at International Brotherhood of Electrical Workers Local 98 at 18th and Spring Garden Streets.
Agents carried the cartons labeled "Tax Records," "Pay Roll" and "Accounting" into a waiting Penske rental truck.
At least two computers were also confiscated.
The raid also included the South Philly homes of the union leader John Dougherty and his family along E. Moyamensing Avenue.
Federal authorities pulled several boxes and a computer.
Accompanied by family, friends and his attorney on the sidewalk outside, Dougherty said he had no idea what this is about:
"The government has a job to do, let them do their job. I am very comfortable with where we're at right now, once we get this ugly scenario go by, everything will be fine."
Doughery says he is cooperating with law enforcement:
"I got the support of everyone, this is what I do day in and day out. I represent working and middle class people, some people don't like that, that's what I do."
A longtime political ally of Dougherty did not appear at a children's event he organized, as FBI agents raided his office as well.
The only tip that something was going on inside Councilman Bobby Henon's City Hall office was an FBI agent posted at the door. Ten agents went through Henon's office for more than five hours.
Meantime, CBS 3 Eyewitness News cameras captured images from a chopper, depicting a brief flurry of activity of men in suits at Henon's district office on Torresdale Avenue.
That office was closed, with a notice posted about a pop-up play event sponsored by Henon in Fairmount Park. A Henon aide was there, expecting him, but Henon was a no show.
Bobby Henon has been on City Council in 2012. Before that, he was an electrician, working his way up through the union. For a number of years, wherever John Dougherty went, Henon was at his side, as the Political Director of Local 98.
Agents also took a computer and box from Doc's Union Pub in Pennsport.
The FBI still hasn't confirmed details about the ongoing investigation. Sources tell CBS 3 there will not be any arrests Friday and officials are only collecting evidence at this time.
