A fourth incident happened around 11:50 p.m. Thursday in the 1800 block of West Roscoe.

The offenders demanded their belongings and the victims complied.

The man and woman were not injured and the offenders fled the area.

The latest incident happened around 2:45 a.m. Friday in the 900 block of West Zakin, not far from the other locations. Police said a 67-year-old man was walking when a white sedan approached him and two offenders exited the vehicle.
