Sisters pistol-whipped during Chinatown robbery

CHICAGO -- Police are looking for the men who robbed and beat two sisters early Thursday morning in the Chinatown neighborhood amid an outbreak of robberies and carjackings in the area over the past week.

Surveillance video shows the women were walking through an alley in the 2400 block of South Wentworth just before 2 a.m. when a silver SUV pulls up and two African American men, who were both armed, run up to them and announce a robbery.

The 26-year-old and 31-year-old sisters were then pistol-whipped, they say, before the men took their bags and ran. One victim told WGN she was hit twice in the head and her sister was pistol whipped in the mouth. The women did not seek medical attention but said they are both badly shaken by the incident.

Police believe the same men may be involved in five robberies or carjackings since October 23. Three incidents happened in the 2100 block of South China Place. Another case was reported at 29th and Stewart.

Investigators are looking for up to 4 men driving in a silver Or black SUV, sometimes wearing ski masks. Anyone with information is asked to call Chicago police.
