They also sought an order from the Prosecutor General's Office to have police ordered to investigate the matter.
PNC is currently under heavy scrutiny over the invalid forms and membership transfers. In a statement, PNC admitted that invalid forms had been submitted to the Elections Commission during its membership drive.
The Election Commission had earlier said that it had received 300 cases of fraudulent party membership changes in the past six months. The issues recently came to light after MDP MP Hussain Ziyad (Fitte) was fraudulently registered to PNC. The Elections Commission later voided the form.
