NEW YORK (AP) — Four people connected to a company hired by New York City to operate homeless shelters for migrants were arrested Tuesday as part of a federal public corruption investigation that is also examining a City Council member and a top aide to New York Gov. Kathy Hochul.

The charges Tuesday focused on two leaders of the nonprofit, BHRAGS Home Care Corp., who are accused of stealing more than $1.3 million from the taxpayer-backed organization, and two subcontractors who the indictment says paid bribes and kickbacks to the men in exchange for contracts worth millions.

Investigators are also probing whether City Council Member Farah Louis and her sister Debbie Louis, an aide to Hochul, accepted bribes related to the appropriation of city funds to the nonprofit, according to a copy of a search warrant viewed by The Associated Press.

The Louis sisters were not among the four people arrested on Tuesday. Debbie Louis was placed on leave after the governor’s office learned of the investigation last week, a Hochul spokesperson said.

The indictment describes multiple layers of corruption within BHRAGS, a service provider that has received nearly $200 million in contracts from the city’s Department of Homeless Services since 2022.
