INDIANAPOLIS, Ind. – The owner of Acapulco Joe’s in Indianapolis is in critical condition after being attacked by a customer.

The attack happened around 2 p.m. at the restaurant on North Illinois Street. Police say the suspect was on a blind date, and he tried to leave without paying after his card was declined.

That card turned out to be stolen, police say.

Owner Grant Redmond was trying to stop him from “dining and dashing,” when the customer attacked him outside. Employees say the suspect hit Grant so hard he knocked him unconscious.

“The guy continued to hit him even after he was unconscious,” said the victim’s partner Bob Plank.

He is in critical condition in the ICU after he had emergency brain surgery.

“They said without the surgery he would die,” said Plank.

The woman who was on the date with the suspect stayed behind but gave a fake name to police.

Surveillance video from Acapulco Joe’s shows the suspect walking around the restaurant, but does not show the attack. The suspect’s name has not been released, but police say he has at least one outstanding warrant for theft.

“This horrible person almost killed a man because he did not want to pay a $40.00 food bill. I do not understand how somebody can do that,” said Plank.
