A second alleged incident of rape in a Tel Aviv parking lot within four days, this time of a 19-year-old woman, resulted in the arrest of four African nationals on Tuesday.

Tel Aviv police arrested four Eritrean and Sudanese men on suspicion of robbing and sexually assaulting the woman, a resident of northern Israel, in a parking lot on Hasharon Street. One of the four is suspected of rape.

Two were caught at the scene of the crime on Tuesday morning. The other two were apprehended later. All four were to be brought to a magistrate’s court for arraignment.

The men and their victim were spotted by police during a routine patrol. They saw the assailants surrounding the woman, who was in a state of undress.

In a separate incident, a 21-year old Nablus man is in custody for allegedly forcing a young couple to have sex at knife-point, and then raping the woman, in a municipal parking lot below Tel Aviv City Hall in the early hours of Saturday morning. He will remain in detention for the next nine days.

On Wednesday, the two victims will view a police line-up including the Palestinian suspect, who was working illegally at a restaurant close to the crime scene.

In further violence in Tel Aviv on Tuesday, a 25-year-old woman was stabbed and seriously injured in the upper part of her body near the old Tel Aviv Central Bus Station. The assailant is believed to have been her Eritrean boyfriend.

A few days ago police arrested a Sudanese man on suspicion of breaking into the apartment of a woman whom he allegedly raped two weeks earlier, in the Hatikva neighborhood in Tel Aviv. DNA results matched the genetic profile of the suspected man to the scene of the crime.

Tel Aviv Mayor Ron Huldai on Tuesday asked Prime Minister Benjamin Netanyahu to play his part in thwarting the upsurge in violence.

Huldai said the prime minister needed to “take responsibility for the difficult reality with which residents of my city have to cope.” The mayor was apparently referring to crimes perpetrated by migrants from Africa and the friction between this population and veteran Israelis.
