INDIANAPOLIS (WTHR) - IMPD is investigating a shooting during an attempted robbery at a northeast Indianapolis restaurant that left a restaurant worker dead.

The shooting happened just before 8 p.m. inside the Subway restaurant near E. 75th Street and Shadeland Avenue. Officers had been called to the location on a report of a robbery in progress. They arrived to find one person shot.

Ashok Kaumar, 35, was pronounced dead at the scene. Kaumar was an employee of the restaurant.

Police said they are searching for three suspects who were wearing all black clothing. Two of the suspects had black face masks, the third was wearing a leopard print facemask. They were also carrying black backpacks.

Investigators released surveillance photos of the suspects early Tuesday morning.

The Subway restaurant was closed Tuesday but the parking lot was full of cars in the afternoon. IMPD North District Beat 60 held their 1:30 p.m. roll call in front of the restaurant.

This was the second robbery shooting at a Subway this month. On Jan. 3, an employee was shot twice during a robbery at the Subway near 38th Street and Post Road.

The victim, an 18-year-old girl in high school, survived. The girl tried to stop the robbery when she was shot. About $300 was taken from the cash register.​

​Piyush Patel owns the Subway at 38th and Post, and five more in the Indy area, but not the one where the employee was killed Monday night.

"This is my location," said Patel. "This is family. Employees are just not employees. They are part of family, kind of. I can't let them die or get hurt up there."​​

Patel is holding a training session with police for his employees this Sunday and inviting other franchise owners to bring their workers. ​​

"It's nothing we can change big time," said Patel, "but at least we can educate our employees how to behave while that happens. That's all we can do at this moment."​

Police say there was a confrontation during Monday night's robbery when the employee was shot and killed. Both of this month's Subway shootings happened in the early evening about six miles apart. Police have not said if they believe there is any connection.​​

"It could be anywhere," said Patel. "It has nothing to do with Subway itself."

Eyewitness News reached out to Subway corporate offices and we're promised a statement Tuesday afternoon. We have not yet received any comment from the company.
