Police said it was "one of the best-selling pizzas."

German police on Monday raided a popular pizzeria in Düsseldorf accused of serving cocaine as a side dish.

Local police launched an investigation into the restaurant after food inspectors tipped off authorities, BBC reported, citing criminal director Michael Graf von Moltke.

Police arrested the 36-year-old pizzeria manager at his apartment. Upon arrival, police said the manager threw a bag of drugs out the window which "fell right into the arms of the police officers" below.
