A police officer was hospitalized after receiving cuts in his mouth from a sandwich filled with glass shards.

The officer said he heard a crunching sound and felt a “grisly texture” when he bit into his sandwich at a Columbus, Ohio, restaurant Monday afternoon. When he opened it up, he saw bits of glass inside the sandwich, according to a local ABC affiliate.

Detectives investigating the incident will determine whether the glass fragments were put in the sandwich on purpose or if it was accidental. The unnamed restaurant closed for the investigation, and police have interviewed least one employee.

Columbus Police say the officer was kept in the hospital overnight, but is expected to recover from his injuries. They have not yet released any additional information on the investigation or the officers health.(RELATED: Taco Bell Employee Tells Cops: ‘I’m Not Serving You’)

Violent incidents against police officers have increased in the past several weeks following the deaths of Alton Sterling and Philando Castile. Gunmen targeted police in two harrowing shootings in Dallas, Tex., and Baton Rouge, La., and officers around the country face growing animosity.
