WHEATON, Ill. (CBS) — Bond has been set at $10 million for two Melrose Park men who were caught with nearly two tons of marijuana inside an Addison business.

Luis Pichardo, 32, and Ignacio Morales, 28, have been charged with one count each of felony unlawful possession of cannabis with intent to deliver, according to DuPage County prosecutors.

They appeared for a bond hearing on Sunday, when their bond was set at $10 million each.

Prosecutors said that on Friday evening, undercover officers with the DuPage Metropolitan Enforcement Group saw the two men acting suspiciously at a business at 135 Laura Dr. in Addison.

When the men left the building, an Addison police officer pulled them over for unspecified traffic violations, prosecutors said. Pichardo, who was driving, did not have a valid driver’s license and was arrested.

During the traffic stop, a police doc alerted officers to the presence of drugs in the vehicle. Police obtained a search warrant for the building on Laura Drive and discovered 3,700 pounds of marijuana inside — an estimated street value of $16.8 million.

Pichardo and Morales are scheduled to appear for arraignment on Sept. 19 at the DuPage County Courthouse in Wheaton.
