An armed robber wearing the same kind of mask has hit three stores in the last month, authorities said.
The so-called Spider-Man bandit struck again this week on Chicago's Northwest Side.
Police said the man held up a convenience store on the 3700 block of North Harlem Avenue at about 7 p.m. Thursday. Police News Affairs said he was wearing a blue-and-red Spider-Man mask when he walked into the store, displayed a gun and asked the cashier to put money into a bag.
Police said this is likely the third store he held up in the past two months.
An armed robber wearing the same kind of mask held up a store about a mile away around 5 a.m. Tuesday on the 2700 block of North Harlem Avenue, police said. He also likely was the person behind a Jan. 24 robbery at a 7-Eleven on the 2700 block of North Harlem around 9:45 p.m., police said.
The suspect is described as a white man who stands between 5 feet, 8 inches and 5 feet, 11 inches tall. He's between 20 and 29 years old, authorities estimated, and has been seen wearing a hooded sweatshirt and Spider-Man ski mask.
A spokesperson for 7-Eleven said the man wore a Spider-Man mask and a tannish coat.
Anyone with information about the robberies is asked to call the Area North Bureau of Detectives at 312-744-8263.
No one was hurt in the robberies, police said.
