OTTUMWA, Iowa (AP) — Police are investigating an Iowa couple’s report that they found marijuana among the layers on their double cheeseburgers.

The couple told police they bought the burgers at the McDonald’s drive-thru on Richmond Street in Ottumwa on April 26. Ottumwa police Lt. Jason Bell says they reported that, after taking at least a bite each, they noticed plant material that smelled and looked like pot.

The two told the restaurant management about what they found and then contacted Ottumwa police. A sample of the substance has been sent to the Iowa Division of Criminal Investigation for testing. No arrests have been reported.

Restaurant managers have declined to comment.
