The Hamilton Heights home of First Deputy Mayor Sheena Wright, who is engaged to Schools Chancellor David Banks, and the Hollis, Queens, home of Deputy Mayor for Public Safety Phil Banks, were searched as part of an ongoing investigation, the sources said.

"Investigators have not indicated to us the mayor or his staff are targets of any investigation," the mayor's chief counsel, Lisa Zornberg, said in a statement. "As a former member of law enforcement, the mayor has repeatedly made clear that all members of the team need to follow the law."
