The IDF, together with Shabak, arrested leading Hamas member Hussein Muhammed Abu Kawik, a member of the Palestinian election commission, in Ramallah on early Wednesday morning.
Kawik was arrested for "ongoing security activities which endanger regional security."
Hamas has since issued a statement accusing Israel of interfering with election activities,which have been called for October.
The move comes as the latest in an IDF crackdown on terror, following mass arrests in terror hotbed Al-Fawwar and various disarming operations in Judea and Samaria.
