An unidentified robber hopped into a car driven by a Sycamore resident early Thursday morning, displayed a gun and stole about $65 from the victim, DeKalb Police said.

The Sycamore man was driving his car south on Sycamore Road at about 8:45 a.m., police said. While he was stopped at a red light in the left turn lane at the intersection of Sycamore Road and Seventh Street, a man who was walking in the crosswalk got into the victim’s car, said DeKalb Police Sgt. Jim Kayes.

“He just jumped into the front seat,” Kayes said.

The robber told the man to turn on Seventh street and pulled out a gun. “He displayed a blue steel, semiautomatic similar to a nine millimeter,” Kayes said.

The victim told police that he gave his wallet to the robber. The robber took the money inside and left the wallet in the car, Kayes said.

The robber quickly left the victim’s car. “He stopped at Seventh and Pleasant, and he bailed out. There robber ran to the west,” Kayes said.

The victim described the robber as a white male between 25 and 30 years old, police said. The robber weighed about 180 pounds, had a medium blue down coat and blue jeans, Kayes said.

The victim was not hurt in the incident, Kayes said.
