Bellevue police seized 567 cell phones, 67 computers and up to $628,900 in equipment from a Lakemont mansion during a June 4 raid.

Newly released search warrant records tie the seizure to an alleged trafficking and digital exploitation operation.

The Journal 425 first reported the warrant details on Friday, Oct. 16. The records were filed with King County Superior Court on July 9.

They lay out the physical scale of what investigators describe as an industrial operation run from a leased 7,480-square-foot estate at 16458 SE 44th Pl.

The 31-page inventory lists 464 Samsung devices and 103 Apple iPhones, along with 11 high-capacity routers, six 30-port commercial USB syncing blocks and crates of factory-sealed phones.

The phone and network hardware alone are valued between $104,200 and $199,600, according to the warrant return. Total seized property is valued between $419,800 and $628,900.

Bellevue Police Detective Alexander P. Slusser authored the 53-page search warrant application. King County Superior Court Judge Paul Crisalli signed the warrant.

Under a folding table in the home, detectives unzipped a black duffel bag holding 25 iPhones labeled with fabricated stage names of young women, according to the warrant records. Upstairs in the master suite, investigators found a passport for Nikita Tyukalo, 21, and registration paperwork for a McLaren 750S supercar. In a downstairs bedroom, two wholesale boxes held 60 unopened Samsung Galaxy S22 smartphones. Six more sealed boxes containing 180 new phones lined the garage floor.

The court documents also connect suspects to financial instruments, prescription stimulants and identity documents monitored by Bellevue detectives and the U.S. Marshals Service, The Journal 425 reported.

Tyukalo was arrested during the June 4 raid. The Seattle Times reported he faces four counts including human trafficking in the second degree, leading organized crime and money laundering. The charges allege he beat young women, held guns to their heads and forced them to create sexual content for up to 20 hours a day, according to Bellevue police.

Four young women told investigators they were recruited at 17 and persuaded to make explicit content on their 18th birthdays, the charges state. They were promised up to $18,000 a month but said they received roughly $1,000. The operation allegedly pulled in as much as $260,000 a month through two entities called Nova Talent Management and Luxe Allure, according to the Seattle Times.

The investigation began after Bellevue Police received complaints and 911 calls from neighbors, according to a Bellevue Beat Blog post published June 5. Officers responded to more than 100 incidents at the residence, including assaults, weapons complaints and minors with alcohol. Some events drew more than 300 people, including people under 18.

"Officers witnessed numerous parents dropping off high-school-aged children at this home, likely unaware of the environment and activities taking place inside," Bellevue Police Captain Joe Nault said in the June 5 statement.

King County prosecutors asked that Tyukalo be held on $5 million bail, citing concerns about witness intimidation and his resources to leave the country, the Seattle Times reported. Two unindicted co-conspirators, ages 20 and 22, were named in the charges but have not been charged with crimes.

The Journal 425 said a follow-up report will examine additional felony allegations and a previously unreported federal arrest at the property. Anyone with information can contact the Bellevue Police Department's Human Trafficking Unit at [email protected].
