POLK COUNTY, Fla. -- The Polk County Sheriff's Office is investigating a Valentine's Day lollipop found to have a blade-like piece of metal embedded in it.

Mulberry resident Lisa Potter bought a bag of 10 Pokemon Valentine Cards and Pops from a Dollar General store last week. She noticed Wednesday night that metal was protruding from one lollipop and reported it to authorities.

The sheriff's office says the blade may have been the edge of a box cutter. It was the only lollipop in the bag that had the piece of medal. Meanwhile, authorities have issued a safety advisory to others who bought the treat.

The store later pulled the candy off shelves. It is conducting its own investigation.
