Two men alleged to have been carrying more than $1 million in black tar heroin have been arrested at the Las Vegas airport in the largest metro police bust of its kind, authorities said Sunday.

Narcotics detectives found 12.6 pounds of heroin stuffed in two suitcases bound for Indianapolis on a flight from Las Vegas, police announced Sunday as they identified the suspects.

The seizure was made before the suitcases were loaded aboard a plane Saturday.

It was the "largest heroin seizure in recent memory," Metro Lt. Laz Chavez told the Las Vegas Sun in a story published on the newspaper's website Sunday.
