JERUSALEM (JTA) — Police in Israel are investigating the death of a Jewish construction worker in Petach Tikvah as a terror attack.

Nathaniel Roi Arami, 26, fell 11 stories from the side of a high-rise building where he was doing exterior work when both of his rappelling cables snapped in an incident on Sept. 16. His co-workers had finished work and had walked away from the site before he fell.

A court-imposed gag order was lifted Tuesday in the investigation, which is looking at Arami’s death as a possible nationalistic murder.

An Arab co-worker had been taken in for questioning following the death but was released later, according to reports.

Arami was the father of two and his wife was pregnant.
