F.B.I. agents raided the offices of the Housing Authority of South Bend, Ind., on Wednesday, the second potential distraction back home for the presidential campaign of the city’s mayor, Pete Buttigieg.
No one was arrested during the raid, in which evidence collection teams visited the housing authority’s headquarters on Alonzo Watson Drive about 1 p.m. with a police officer and United States government trucks.
The agency, which runs nine low-income housing facilities in South Bend and is financed by the federal Department of Housing and Urban Development, has been beleaguered by complaints of financial mismanagement for much of the decade.
Such concerns prompted Mr. Buttigieg to replace all six commissioners on the housing authority’s board in 2015.
Mr. Buttigieg, 37, distanced himself from the agency in a statement issued by the mayor’s office, which emphasized that the housing authority is an autonomous entity.
“Earlier today the mayor’s office became aware through local media reports of today’s law enforcement action at the Housing Authority," Mr. Buttigieg’s statement said. “While the Housing Authority is not part of the city administration, the mayor is concerned and will be closely following the situation.”
In June, Mr. Buttigieg briefly left the campaign trail after a fatal shooting of a black man in South Bend by a white police officer, which sparked protests in the city of just over 100,000 people.
Law enforcement officials declined to comment about the nature of the raid on Wednesday.
“Department of Justice regulations prohibit us from either confirming or denying the existence of an investigation,” Ryan Holmes, a spokesman for the United States Attorney’s Office for the Northern District of Indiana, said in an email. “However I can confirm there is federal law enforcement activity going on in the South Bend area.”
Tonya Robinson, the housing authority’s executive director, did not immediately respond to an email request for comment on Wednesday. The voice mail at Ms. Robinson’s home phone number was full.
Tim Scott, a member of the South Bend Common Council, said he was concerned that housing authority tenants would be displaced by the raid at the agency’s headquarters, which is connected to one of its housing complexes.
“We don’t really have a say on anything that goes on in the housing authority,” Mr. Scott said.
Mr. Scott, who is supporting Mr. Buttigieg’s presidential bid, said he didn’t know if the F.B.I. raid would have reverberations for Mr. Buttigieg’s campaign until further details emerged.
The turmoil on the home front followed a spring surge by Mr. Buttigieg, a Harvard-educated Rhodes Scholar who served as an intelligence officer in the United States Navy Reserve and was deployed to Afghanistan.
From April through June, Mr. Buttigieg raised nearly $25 million. But he has been unable to reach his Democratic presidential polling high-water mark of 10 percent from the end of April. A July 29 Quinnipiac University poll put Mr. Buttigieg at 6 percent, compared to 34 percent for former Vice President Joseph R. Biden Jr.
