Police impersonator robs a 3rd person on South Side

A robber posing as a federal agent on the South Side struck again Saturday night when he robbed a man after claiming to be conducting a homicide investigation. It is the third time this month that the same suspect has posed as a federal police officer and demanded the victims get into his SUV before making off with their cash.
The latest robbery happened about 11 p.m. Saturday on the 7000 block of South Justine Street when the suspect pulled over his silver SUV and ordered the victim who was on the street into the SUV.
The suspect told the 41-year-old male victim that he was a federal officer and was conducting a homicide investigation. The man also told the victim he was "Officer Franklin." Other victims have reported the suspect using the same name.
While the suspect did not display a weapon, the suspect demanded that the victim get inside his SUV, police said. Police are treating the latest incident as a strong-arm robbery.
"He raised his voice in an aggressive manner to get inside his vehicle".
After the victim got into the SUV, which was described as either a silver Mercury Mountaineer or Toyota Forerunner, the suspect drove off a short distance. After pulling over on the 8000 block of South Oakley Avenue, the suspect demanded cash and then fled after the victim gave him money.
The victim was allowed to leave without being harmed.
Previously, the suspect showed a silver semi-automatic handgun to each victim before robbing them.
The suspect is described as black, about 40 years of age, about 5 feet 8 inches tall and weighing about 170 pounds, with brown eyes, black hair and medium complexion.
The man is also suspected in robberies that happened at 2:10 p.m. Sept. 24 on the 8100 block of South Paxton Avenue and at 3 p.m. Sept. 15 on the 7700 block of South Colfax Avenue.
In the previous robberies the man was driving an SUV with temporary plates.
