As a part of the investigation, eight others involved with the bikini stands in question were arrested on accusations of prostitution and lewd conduct, said Deputy Chief Dan Templeman with the Everett Police Department.
The investigation began about 3 1/2 months ago in the aftermath of a Kent police operation that culminated in the arrest of two employees at a bikini barista stand for lewd conduct.
While interviewing those detained, detectives learned sergeant Darrell O'Neill with the Snohomish County Sheriff's office was tipping workers as to police intentions, Templeman said.
"He was providing law-enforcement sensitive information on when undercover operations were being conducted and even some of the makes and models of an undercover vehicle," Templeman said.
O'Neill is a 30-year veteran of the Snohomish County Sheriff's Office.
"It is a big shock to us in more ways than one and certainly a disappointment," Templeman said.
The investigation also led to search warrants being executed at seven different Java Juggs and Twin Peaks espresso stands in Snohomish and King County, as well as a home in Snohomish.
"Through video surveillance, interviews, and in-person surveillance and we were able to witness prostitution and lewd conduct at those stands -- pretty blatant activity occurring at those stands," Templeman said.
Several people were detained, including owners, managers and workers, Templeman said.
Everett Police spokesman Aaron Snell tells the Everett Herald that all those arrested were adults.
