As many as 200 women were coerced in to paying money in a scandal involving popular social networking website Facebook.
Most of the victims are said to be lady doctors affiliated with five hospitals of the provincial capital.
According to a police report, an unknown man was blackmailing the women for money and threatened to leak their private records on social media after hacking their Facebook accounts.
Police have launched an investigation into the issue after registering a case against the unidentified person.
Some victims have paid money to the blackmailer through mobile phone credit before the scandal came to fore in Punjab where a massive child sex abuse scam was disclosed earlier this month.
