BEVERLY — An armed robbery occurred on Monday night at a business in the 2400 block of West 103rd Street in Beverly, police said.

Ald. Matt O'Shea (19th) confirmed Tuesday that the incident occurred at the 7-Eleven convenience store at 2421 W. 103rd St.

He also took to Twitter to say that two "mopes" were in custody following the robbery.

The Chicago Police department's news affairs division later confirmed that detectives were speaking to "two persons of interest. Both adults, one male and one female."

The robbery occurred at approximately 10:20 p.m. An unknown, armed male black offender entered a store and demanded cash, police said.

The thief fled in a possible minivan with an unknown amount of money. No injuries were reported, police said.

O'Shea believes the two suspects will also be linked to a recent pair of suburban convenience store robberies. One of these robberies occurred at the 7-Eleven store at 9860 S. Kedzie Ave. in Evergreen Park. The other occurred at the Thontons station at 12052 S. Western Ave. in Blue Island.

"Most importantly, they got them," said O'Shea, commending the work of Chicago Police officers.

O'Shea credited his father for use of the term "mopes," saying his dad often referred to him as such when he was caught past curfew or for some other family infraction.

The store is commonly frequented by Chicago Police officers both on- and off-duty.

"If you are in a scavenger hunt and I said go find a police officer, you should go to 2421 W. 103rd St.," O'Shea said.
