Mayor Eric Adams has been accused of sexually assaulting a woman in 1993 in a lawsuit seeking at least $5 million filed just before the deadline for the Adult Survivors Act, The Post learned Thursday.

The accuser, whom The Post is not identifying because of the nature of the allegation, named Adams as a defendant along with the NYPD’s transit bureau and Guardian Association in a lawsuit filed late Wednesday.

Adams was an NYPD officer at the time and the filing said the woman also worked for the city.

“Plaintiff was sexually assaulted by Defendant Eric Adams in New York, New York in 1993 while they both worked for the City of New York,” claims the 3-page summons, which does not give more detail on the alleged assault.
