MASSACHUSETTS, USA (AP) A man has been arrested after a kilogramme of cocaine hidden inside a hollowed-out chunk of bologna was delivered to his home.

Holyoke police say they were tipped off by postal inspectors in Puerto Rico who had been investigating similar shipments. A dog confirmed the presence of drugs and the bologna was cut open.

The meat was then repackaged and an undercover postal inspector delivered it to a Holyoke address at about 4:45 pm Thursday. A woman sitting on the front steps signed for it.

Police then executed a search warrant and arrested a 30-year-old man on a cocaine trafficking charge.

Police say the cocaine had a street value of $100,000. The investigation is ongoing.
