Chicago Police Release Surveillance Video Of Elderly Man's Brutal Robbery Attack

The 86-year-old Chicago man is lucky to be alive.

On April 3, an unidentified man was followed by two other men from a Currency Exchange, bank and Target store to the apartment building where he lived in the city's Woodlawn neighborhood. The two men proceeded to choked, beat and robbed the elderly resident in the building's lobby, ABC Chicago reports.

"I’m thinking, I’m being robbed. But I didn’t feel a knife or a bullet going off. I blanked out," the man, a World War II veteran, told CBS Chicago of the attack. "And the next thing I knew, I’m coming to on the floor."

The attackers robbed the man of $500 they had watched the man put in his sock after withdrawing it from the bank earlier that day, according to the station.

Chicago police spokesman John Mirabelli told ABC "this is one of those crimes that hits us in the pit of the stomach." Police are hoping the released surveillance video of the attackers will help them nab the attackers. Crime Stoppers is offering a $1,000 reward for any information that leads to their arrest.

The attackers are described as black men, one between 30 and 40 years old with a thin build and the other between 40 and 50 years old with a heavy build. They are both between 5-foot-8 and 5-foot-11.
