A Wisconsin hospital pharmacist accused of intentionally ruining hundreds of COVID-19 vaccines was arrested, police say.

Aurora Medical Center in Grafton fired the employee after discovering he intentionally left more than 500 doses of the Moderna vaccine without refrigeration last weekend, forcing the hospital to discard the vials, officials said.

The pharmacist was arrested Thursday, authorities say.

Grafton police are seeking charges of felony recklessly endangering safety, adulterating a prescription drug, and criminal damage to property.
