IDF forces in Nablus on Wednesday arrested 36-year-old Tanzim member Hayman Zaban, who was involved in carrying out the lynch in Ramallah some seven years ago in which Israeli reserve soldiers Vadim Nurzhitz and Yossi Avrahami were killed.
Zaban is the last of the suspects in the incident to be arrested, and was transferred to defense forces for investigation.
"Zaban was shocked when the soldiers came to arrest him," an IDF official said, adding that the Tanzim member was unaware that Israeli security forces were still on his trail.
The military said Zaban had eluded IDF forces up until now by moving from one West Bank city to another.
Following the lynch, then-Prime Minister Ehud Barak vowed that the IDF would reach all those involved.
Nurzhitz and Avrahami entered Ramallah by mistake while driving to an IDF base in the area. They were stopped by Palestinian officers and taken to the local police station, where they were beaten and stabbed to death by an angry mob that stormed the station while hundreds of locals cheered the killers on.
The shocking images were captured on video by an Italian TV crew.
Last Tuesday a soldier belonging to the reconnaissance battalion that seized Zaban was killed during an operation to arrest wanted terror suspects in the Ein Beit Ilma refugee camp in Nablus.
