Federal prosecutors have reportedly joined a state investigation into possible fraud by former Brooklyn District Attorney Charles Hynes.
The city's Department of Investigation released a report earlier this month showing Hynes used more than $200,000 seized from criminal raids to pay for a political consultant working on his re-election campaign.
Hynes was defeated by Kenneth Thompson, who took office in January.
Reports say federal involvement could mean felony charges for the former prosecutor.
DOI also alleges Barry Kamins, who is the administrative judge for the city's criminal courts, may have violated ethics rules by advising Hynes on the campaign.
Kamins has been removed from his post.
