Immigration advocates say 40 people in and around the city have been arrested by federal authorities as part of a nationwide crackdown on immigrant communities.
Federal Immigration and Customs Enfocement (ICE) confirmed the number of arrests to NY1.
The New York Immigration Coalition says raids were conducted last week in five other states as well.
The coalition also released a document from ICE, which it describes as a "leaked memo," but the federal agency has since confirmed its accuracy and it appears the document is a draft fact sheet, written to accompany a press release and other materials that will be released to the media this week.
The Mayor's office says it has received reports about immigration enforcement activity in the city, and that it is closely monitoring the situation.
The mayor says city officials and the NYPD will not act as immigration agents and should never ask New Yorkers about their immigration status.
