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.
