The arrest of a man on drug charges in Naperville this week led to the discovery of more than $1 million in homegrown marijuana at the man's Chicago residence, police said Friday.
Naperville police arrested 32-year-old Ronald Sanchez Thursday afternoon on charges of unlawful delivery of marijuana, but a search warrant executed later at Sanchez's house in Chicago uncovered a "sophisticated" marijuana growing operation, authorities said.
Over 300 mature plants and several large plastic bins of processed marijuana was discovered, according to police.
In total, the recovered drugs have a street value of $1,197,800, police said.
Sanchez, of the 3200 block of North Oleander in Chicago, was formally charged with production of cannabis plants and possession with intent to deliver.
Naperville police were assisted by the DuPage and Cook County state's attorney's offices in the investigation.
