Portland, OR -

A federal grand jury has indicted 16 people on charges of conspiring to import illegal anabolic steroids, mostly from China, and using a Portland business as a front for drug trafficking and money laundering.

The indictments say investigators identified nearly 50 Western Union wire transfers to Chinese chemical companies to buy anabolic steroids, and they tracked at least 68 shipments from China to the defendants between 2008 and August.

The Oregonian reported federal agents and Portland police arrested many of the suspects Thursday morning.

The indictments say two defendants, Shane Jack and Landon Britt, created the business, SJ Motors in north Portland, and are listed as officers.

Defendants are also accused of manufacturing and distributing packages of steroids and manufacturing and selling marijuana and oxycodone.
