TEL AVIV — The man suspected of killing two people and injuring seven others outside of a cafe-bar in the Israeli city's downtown was identified by police Saturday as the search for him ramped up for a second day.
Security camera footage showed Nasat Melhem on Friday wearing protective eyeglasses and a windbreaker while causally browsing dried fruit at a health food store in central Tel Aviv, police said.
Melham, described as a 31-year-old Israeli Arab, then pulled a machine pistol from his backpack, stepped onto the pavement and started spraying bullets.
Sami Melhem, a relative of the alleged shooter and a lawyer who has represented him in the past for assaulting an Israeli soldier, said the suspect's father — who is a police volunteer — recognized his son in the footage and came forward to identify him.
A gun had been stolen from the suspect's father's safe, Sami Melhem said.
Police raided the family's home, arrested the suspect's brother and confiscated a computer from the house, Melhem said.
"The whole incident saddens us all," Melhem told NBC News, adding that he believes Nasat Melhem is "clearly insane," but didn't think the 31-year-old would unleash a deadly attack.
Israeli police are working on "high alert," and Special Forces are involved in the search for Melhem in case he has taken hostages, said Israeli police spokeswoman Luba Samri. Israeli police also said they are concerned Melhem had help from someone else during the New Year's Day rampage.
"The police worked all night and this morning to locate the suspect," Samri said, warning the public to listen to police commands but also go about their normal routines.
"At this moment we don't feel the public needs to change anything in their daily life," she said.
Israeli Prime Minister Benjamin Netanyahu on Saturday night visited the scene of the violence, which had become a makeshift memorial blanketed in candles and flowers.
The shooting came amid a wave of Palestinian attacks against Israeli civilians and soldiers that have happened almost daily for more than three months.
There was no immediate claim by Palestinian armed factions for Friday's attack.
Asked if the suspect had radical religious tendencies, Sami Melhem told Reuters: "I do not know."
