Initial reports were later confirmed by police on Thursday, proving that the Arab terrorist from the Hevron region in Judea who stabbed to death two Jews at prayer in southern Tel Aviv and moderately wounded a third worked at a local restaurant.
The attacker, a 36-year-old resident of Dura near Hevron, had been given a work permit and was gainfully employed at a restaurant in Yafo, a suburb immediately to the south of Tel Aviv - until he decided to take up a knife and go murder Jews.
Just hours later, another terror attack took place in the Gush Etzion region of Judea, in which two Jews and a Palestinian Arab were murdered and eight other Jews were wounded in a shooting and car attack.
A very troubling trend was highlighted by the stabbing attack in Tel Aviv, as the restaurant worker was far from the first Arab worker to manipulatively capitalize on his place of employment and access to Jewish areas to launch lethal attacks.
The list of similar incidents is seemingly endless, even just looking back other the span of a year or two.
Another Arab restaurant worker in Bat Yam, another suburb of Tel Aviv, tricked IDF First Sergeant Tomer Hazan in 2013 to go on a drive with him to his village, before strangling him to death in an open field and hiding his body in a water hole.
Also in Tel Aviv where Thursday's attack took place, early last month an Arab construction worker took advantage of his job to go out and stab five Jews with a screwdriver, lightly wounding them before being shot.
Last year construction worker Netanel Arami had his rappelling ropes cut by Arab terrorist coworkers and fell to his death, in a case police and the courts covered up for a long time.
In the massacre at a synagogue in Jerusalem's western Har Nof neighborhood just over a year ago, one of the two Arab terrorists who murdered four Jews at prayer - reportedly beheading two of them - and shot a Druze police officer to death worked at a store meters from the synagogue.
Despite that, Bezeq said it saw no "warning signs" - and just last month, the same Bezeq worker used his company car and an axe to run over and murder a man in Jerusalem and wound another two.
The terrorist who nearly assassinated Temple Mount activist Yehuda Glick last year outside Jerusalem's Begin Heritage Center had previously served 11 years in prison for terrorism, but nevertheless was employed at the Terasa restaurant in the Center.
That criticism was particularly loud last December when an Arab terrorist stabbed two Jewish shoppers at a Rami Levy branch in Mishor Adumim to the east of Jerusalem; the terrorist apparently was aided by an Arab employee who gave him the knife he used to moderately wound the two.
Knesset members from the political left and right alike have scoffed at calls not to employ Arabs out of fear that they might use their position to launch an attack, but former MK Dr. Michael Ben-Ari called their bluff last November when he revealed the Knesset doesn't hire any Arab workers for manual labor.
