Veteran, 81, is sucker punched and carjacked by teenagers while out delivering pizza in lawless Chicago

An elderly man who has delivered pizza in Chicago for 40 years was punched in the face and robbed before having his car stolen in a brazen carjacking on the city's Northwest Side.

Ernie Aimone, 81, explained how the sudden attack came after he had made a delivery in the Jefferson Park neighborhood.

A man approached from behind before striking Aimone in the head, causing him to fall to the ground.

The assailant demanded his car keys and then punched Aimone in the face, leaving him fearing for his life.

'They said, 'gimme the keys, gimme the keys,'' Aimone said to ABC7 'And they sucker punched me from behind, hit me in the face. I was afraid for my life.' 

Chicago Police confirmed the incident occurred around 9pm on Wednesday on North Ludlam Avenue.

A GoFundMe set up in response to the incident by the Gladstone Park Chamber of Commerce has so far raised over $42,000 towards the purchase of a new vehicle, including a $1,000 donation from the pizza joint itself.

'He's like a local legend,' said Dan Ciolino with the Chamber. 'He's been loyal to Joe's for 40 years. He served our country. He deserves our support in his time of need.'
