Police said they are investigating four armed robberies that occurred between June 1 and 9.

The most dramatic incident occurred June 5, when a gunman forced two employees and a customer at the T-Mobile store, 14569 Cicero Ave., into a back room while he stole about $21,000 worth of electronics and $1,200 in cash, according to police. They said the workers immediately called 911 after the robber fled the store, but police were unable to locate him.

Two days later, a 25-year-old Midlothian man told police a man wearing a hooded sweatshirt, blue jeans and a “doo rag” attempted to rob him at gunpoint near M&M Glass in the 4000 block of 147th Street.

Several hours later on June 7, a 33-year-old Midlothian woman was robbed by a gunman of her purse, car keys and 2013 Chrysler outside her apartment in the 14700 block of Homan Avenue, police said.

On June 1, two men reported that they were robbed at gunpoint by a man while walking in the 14600 bock of Karlov Avenue, police said.

Police declined to comment on whether they believe the robberies were committed by the same man.

OAK LAWN

Gas station robbed

A gunman wearing a black hoodie, ski mask and gloves stole $300 in a June 11 robbery of the Speedway station, 9800 Cicero Ave., according to police.

A clerk who called 911 said the robber entered the store about 10:50 p.m., displayed a small revolver and demanded money, police said.

They said the clerk gave him the $300 from the register in a plastic bag, and the man ordered the clerk into the back room and told her to stay there for several minutes.

When she came out, the robber had left, and she called police.

TINLEY PARK

Serial flasher charged

An Orland Park man was arrested after he repeatedly exposed himself to female employees at a McDonald’s restaurant, according to police.

Rudy Jerez, 32, 14944 Hale Drive, was charged with public indecency after a May 28 incident in which a female worker at the restaurant, 15920 Harlem Ave., said he had his penis exposed when she delivered coffee to him in the drive-through lane, police said.

They said the victim immediately told a co-worker, who told her that she thought the same customer had exposed himself to her on April 29 and May 6.

The first victim was able to obtain Jerez’s license plate number after the May 6 incident but said she did not immediately notify police because she was scared, police said.

They said Jerez has a July court date and has been banned from the restaurant.
