The National Fraud Unit sent two detectives to Kadima's Petah Tikva headquarters on Thursday, as police continue to examine allegations of wrongdoing in the ruling party's current membership drive. The detectives questioned Kadima director-general Adi Sternberg about the membership campaign. "Officers did call on the party's headquarters, but we are not carrying out an investigation and this was not a raid," a National Fraud Unit spokeswoman said. "We are carrying out an examination to determine whether there are grounds for launching a criminal investigation." The spokeswoman declined to say whether detectives seized documents or computers. "They [the officers] may have taken documents," she said. A Kadima spokesman said the party's administration cooperated fully with the police. The party had done everything possible to ensure that the drive was handled properly, including employing party comptroller Yehuda Barlev, who is an internationally respected accountant, the spokesman said. "The party has many safeguards to ensure that the membership is handled in a legal and transparent manner," a Kadima official said. "We view any attempt to misuse the drive gravely and call upon anyone who is aware of any wrongdoing to contact the comptroller."
