Security video footage shows an unprovoked attack early Sunday morning at Mr. Submarine that too employees helped break up.
Two Beverly sub shop employees became instant heroes over the weekend.
Ernesto Romero and his brother Agustin came to the aid of two patrons who were being attacked by three men in Mr. Submarine's drive-thru.
Mark Ziolek, who has two black eyes, and his girlfriend, Tina Coconate, returned to Mr. Sub on Thursday to thank the brothers for their help.
Security video footage shows the unprovoked attack early Sunday morning. The attackers demanded Ziolek give them his sandwich and money, and they threatened Coconate. Ernesto Romero reached his arm out of the drive-through window to pin one of the men against the restaurant, while Agustin rushed outside to fight the attackers.
Conor Heffernan, 24, of the 3000 block of West 98th Place; William Butler, 20, of the 9000 block of South Central, and Robert Heffernan, 20, of Kalamazoo, Mich., were arrested thanks to the Romero brothers' help. The men were charged with two counts of misdemeanor battery and one count of misdemeanor criminal damage to property.
Ziolek and Coconate said they couldn't fend off the attackers without the brothers' help. The couple stopped at the Mr. Sub for a roast beef sandwich on their way home from a benefit for Mother McAuley High School, according to the Sun-Times.
Ald. Ginger Rugai (19th) plans to honor the brothers a certificate signed by the rest of the City Council.
