Ohio policeman served sandwich containing shards of glass

COLUMBUS, Ohio -- Police in Ohio's capital city say an officer was served a sandwich containing glass shards at a restaurant, and an assault squad is investigating whether it was intentional.

The Columbus officer cut his mouth after biting into the sandwich served to him at a restaurant on Monday afternoon. He was taken to a hospital and held there overnight.

Police say the officer heard a crunching sound as he ate the sandwich.

Columbus Public Health officials say they plan to visit the restaurant Tuesday to help determine what happened.

A Columbus Police Department document says officer Quoc Nguyen bit into his Reuben sandwich - and heard "crushing." He then realized his "mouth was bleeding."

Sources at WSYX-TV Officer Nguyen's partner drove him here to Grant Medical Center. Several tests were performed, he was treated, released and appears to be OK.

"I apologize. I can't-- the matter is under investigation," said Leon Lewis, operations manager for Lincoln Café, where the officer purchased the sandwich, when asked by WSYX if the glass was intentional.

The restaurant says it's cooperating with both the Columbus Police Department and health department. Health inspectors dropped by the restaurant and talked with the person who served the officer his sandwich. They inspected the food and didn't find anything wrong with the food.

What they did find were, "several glass plates with chips on the rim" and "four small pieces of clear broken glass" under the drying rack.

A spokesperson with the health department says finding glass in food is extremely rare.

"Business is fine," Lewis said. "Once again, it's under investigation."

Columbus police say they're still investigating, but at this time they say there's no evidence to suggest glass was intentionally put into that officer's sandwich.
