'Tuesday's announcement represented the largest number of officers accused of drug-related charges since 1973, when 10 officers were accused of stealing drugs and money from dope pads
in what was called the 10th Precinct conspiracy. Three were convicted. For some Detroit officers on patrol Tuesday, the revelations were "just another kick in the face for us."

Or are you referring to when Coleman Young's neice and father dealt drugs from cops stash and were paid for protection mafia style ?? in 1991

Ten Detroit and suburban police officers were charged Tuesday with accepting money to guard a dozen large shipments of cocaine and drug cash for undercover federal agents posing as dope dealers.
"Among six civilians also accused were Mayor Coleman Young's niece, Cathy Volsan Curry, and her father, Willie Volsan. Volsan Curry was arrested. Federal authorities expected to have the others arrested within a day.
'Authorities said imprisoned Detroit drug lord Richard [[White Boy Rick) [[Who should have been executed) Wershe was instrumental in the initial contact between the FBI agent posing as a drug dealer and Cathy Volsan Curry, who approached Detroit police. Wershe was a partner of Cathy Volsan Curry's husband, imprisoned drug dealer Johnny Curry , and once dated Cathy Volsan Curry. Wershe's lawyer, William Bufalino II, said he knew nothing of a Wershe role in the investigation.'
