Zechariah Abu Saeed (died 2023) was a Palestinian informant in the service of Israel. In 2023, he was asked to aid the Israelis with the capture of the rogue PPS policeman Adel Tawalbe. However, Omar Tawalbe kidnapped Shin Bet captain Gabi Ayub in Brussels and interrogated him into giving up the names of all Palestinian collaborators in Jenin, and Zechariah was abducted by Adel's henchmen under the pretense of being taken to Adel, before one of Adel's men strangled the informant.
