Police in Indiana are investigating after they said an elderly woman died following a fight over an issue with an order at a Tim Hortons location.

According to a news release from the Fort Wayne Police Department, officers responded last week to calls of a reported battery involving a 75-year-old woman, later identified as Anita Grayson, and a 20-year-old Tim Hortons worker. Police have not released the name of the Tim Hortons worker involved in the incident.

Police said detectives learned that Grayson entered the Tim Hortons store to "address an issue with an order she had received through the drive-thru." Once inside the store, Grayson is said to have begun “berating a 17-year-old female employee.”

A 20-year-old shift lead stepped in and asked Grayson to leave the store, according to police, who said the shift lead put her hands on Grayson to stop her from reaching the 17-year-old worker.

Grayson is then alleged to have shoved the shift lead and struck her in the face, according to police, who also shared security footage from the incident. The video shows the altercation between Grayson and the shift employee on the floor of the Tim Hortons.

Police said the shift lead was left with both scratches and also had a “chunk of hair” pulled from her head. Following the fight, police said Grayson sat down at a table before picking up the “shift lead’s hair from the floor” and placing it on her bag.

Moments later, police said Grayson laid down on the floor with the shift lead checking up on her and bringing her a cup of water. Once officers arrived, they found Grayson unresponsive and she was taken to a local hospital, where she was pronounced dead.

"The Fort Wayne Police Department recognizes that any loss of life is tragic. When the circumstances surrounding a death are not immediately clear, those circumstances must be thoroughly and professionally investigated," police said.

Police said no arrests have been made in connection with the death and Grayson’s cause of death has not been determined.

In an emailed statement to USA TODAY, Tim Hortons said the local franchisee of the location where the incident happened has "been cooperating fully with the police."

"We were deeply saddened to learn about this incident and our heartfelt condolences go out to the loved ones of Anita Grayson," Tim Hortons said.
