(JTA) – The father of the alleged gunman in the deadly shooting on a Tel Aviv bar was arrested in connection with the attack. Mohammed Melhem was questioned on Tuesday, Jan. 5, along with five other family members and friends. They are suspected of being accessories to the killings on Jan. 1. As the Ledger went to press on Tuesday, the search for Nashat Melhem, 31, entered its fifth day.

On Monday, Mohammed Melhem made a televised appeal to his son to turn himself in. “I call on my son directly, if you can, cooperate with me and contact me to arrange matters,” the elder Melhem said. “I will help you. Let’s end this saga. These are difficult days for the family.” He also condemned the attack.

Mohammed Melhem identified his son to police as the shooter in the hours after the attack after seeing his image on the surveillance footage taken during the attack. Two people were killed in the shooting. On Tuesday, Israel Police said they believe that Nashat Melhem has escaped to northern Israel or the West Bank.

Chief Roni Alsheich said residents of Tel Aviv could “dramatically reduce the tension” without giving away any details of the investigation. He made the comments after visiting the family of Alon Bakal, one of the victims of Friday’s attack, to update them on the progress of the investigation. Thousands of police reportedly are involved in the search.
