OSWEGO, N.Y. -- Oswego County landlord Doug Waterbury has a "longstanding pattern" of sexually harassing female tenants -- dating back to 1990, according to federal officials.

The U.S. Department of Justice today filed a lawsuit against Waterbury, joining in the claims lodged last year by six low-income tenants of Waterbury's.

According to the DOJ lawsuit, Waterbury's sexual harassment spans dozens of victims, including a teenager who he subjected to non-consensual sex while she checked out an apartment he was renting.

Waterbury has not been criminally charged, according to a spokesman for Oswego city police.

He owns the Renaissance Fair in Sterling, Syvlan Beach Amusement Park, Santa's Workshop near Lake Placid, and about 50 rental properties mostly in the city of Oswego.

The Justice Department's lawsuit names Waterbury, his wife and business partner Carol, and two property companies, Ontario Realty Inc. and E&A Management Co.

Federal officials said that among multiple other instances, in May 2017, Waterbury locked a teenaged girl who was a prospective tenant in a rental unit, lifted her shirt, groped her and pushed her onto a couch.

According to the DOJ's complaint, Waterbury then proceeded to have "unwelcome and painful sexual intercourse and oral sex with her, and instructed her not to tell anyone what had just happened."

Federal officials provided a handful of other examples in their complaint, including repeated harassment of a homeless woman who continuously refused to rent from Waterbury, despite his offers of lower rent in exchange for sex.

"The experiences of these three women were not isolated instances," DOJ lawyers wrote in their complaint.

According to federal officials, Waterbury regularly demanded tenants and potential tenants have sex with him to keep or obtain housing, including while he was showing rental units.

Here are other examples alleged in the complaint:

He subjected these women to non-consensual sexual contact, groping, unwanted sexual comments and advances.

He asked women intrusive personal questions about their romantic relationships and sexual histories as part of their application process for apartments.

He offered reduced rent or deposit payments in exchange for sex.

He refused services or created adverse housing conditions for females who refused sex.

He showed up for unannounced, intrusive visits to tenants' homes for the purpose of making sexual advances.

According to the DOJ, the lawsuit is part of a Civil Rights Division initiative announced in October to combat sexual harassment in housing.

Officials said in a statement they hope the lawsuit and other efforts help with "tackling this scourge, which strikes at the heart of access to fair housing, free from harassment and other forms of discrimination."

The lawsuit demands money to compensate Waterbury's alleged victims and seeks a court order barring him from further discrimination.
