As a result of the lawsuit, Harrison Mayor Joan Walsh plans to hold an emergency executive session to demand that the town board authorize a full investigation by an independent investigator and to appoint an independent monitor if the allegations prove credible.
"The manner in which our residents and neighboring communities view our police department is deeply troubling to me and cannot be tolerated any longer," Walsh said in a statement e-mailed to ABCNEWS.com.
She added, "The civil rights and safety of Harrison residents is my foremost concern, and anything or anybody who threatens those rights or that safety must be investigated and appropriately disciplined."
Steven J. Harfenist, a lawyer for the officers, said the lawsuit is completely baseless, without merit and involves fabricated allegations.
"This was a search warrant validly executed that resulted in the arrest of Mr. Porto who is doing jail time, having pled guilty to a felony on a drug-related charge," said Harfenist. He added that officers found a handgun, silencer, large amounts of cash and marijuana with a street value of $5,000 at the house.
"The tape was never played in front of her and she was not sexually molested. She was frisked in accordance with police procedures and the search went by the book," he said.
The alleged incident is just the latest scandal for the town's police department and longtime captain in recent years. Residents have mixed feelings about the force.
A neighbor of the Portos, who declined to be named, defended the police. "They are great. Allegations are just that -- allegations."
Other residents, who also declined to be named, were more critical of the police force.
"It is a scary situation," said one longtime resident. "Some of these officers think they can get away with anything -- and people in town are afraid to confront them. What are you gonna do? They're the police."
A lawyer who has not been involved in litigation with the police was also reluctant to go on the record with his comments. "There is a perception in the town and in our community that there are some bad things going on at the police department. As a citizen, I have concerns about it."
