Police at Mexico City's international airport have found a load of lollipops with each piece of candy containing a capsule of methamphetamine.

The federal police say the freight shipment originated in the drug-plagued state of Sinaloa and was headed to Omaha, Nebraska.

Police X-rayed a nine-pound (4.1 kilogram) box of candy labelled "Handicrafts and Candy." Inside, they saw the circular shadows of capsules inside the lollipops.

Police said Monday that experts are still testing the capsules to determine their exact composition and weight.
