A 59-year-old Cheektowaga man and a 25-year-old Buffalo woman were being held Tuesday on robbery and prostitution-related charges linked to an alleged online extortion scheme linked to lonely men seeking dates through Adult Chat lines.

Robert M. Wozniak was arrested Saturday, and Amber L. Kwasniewski was arrested Tuesday following a two-month investigation by West Seneca police and state police. Both are charged with second-degree robbery, second-degree burglary, grand larceny and criminal impersonation of a police officer. Wozniak was separately charged with promoting prostitution, and Kwasniewski was separately charged with prostitution.

Following West Seneca Town Court arraignments, Wozniak was held in lieu of $25,000 bail and Kwasniewski in lieu of $30,000 bail.

West Seneca detectives said that after victims made contact with victims at online Adult Chat lines and set up “dates,” she would show up at their homes with Wozniak driving her. On meeting the victim, Wozniak would use what detectives described as his “imposing size” to either make threats of being a police undercover officer or an angry father of the supposedly “underaged” Amber.

At that point, Kwasniewski is accused of extorting money from the victims.

The ongoing investigation has also uncovered a similar possible case in the Blasdell area. Detectives said anyone with information on the scams can call the West Seneca Police Detective Bureau at 674-3154 or their local police.
