A suspect was arrested for the murder of a Sudanese national on Wednesday, Israel Police said.
Officers raided the Tel Aviv home of the 37-year-old foreign citizen on Tuesday and brought him in for questioning.
"We are in a series of events that require us to invest a lot of effort and resources. This operation emphasizes the determination and effort of police officers to bring criminals to justice and strengthen the public's sense of security in Tel Aviv," said the district commander. "We will not let up, and we will turn every stone until we deal with perpetrators as we did in this incident."
The 33-year-old Sudanese man was fatally shot on Saturday in what police suspected was drug-related conflict with local criminals. Alleged video of the incident circulating online shows a Wolt deliveryman calmly walking up to a group of people, pulling out a pistol, and shooting at them from close range.
The incident occurred amid rising violent crime among illegal immigrants and asylum seekers.
