Police remain tight lipped about a drug-trafficking investigation embroiling AFL great Mark Thompson.
Thompson, 54, was arrested on Tuesday before being released without charge, pending further inquiries.
It followed a police raid on Friday of a property he owns at Port Melbourne.
"All we've done so far is confirm that we did execute warrants at that premises and that he came and spoke to our police late yesterday afternoon," Chief Commissioner Graham Ashton told reporters on Wednesday.
"The investigations on that case, I'm told, are continuing.
"We need the investigation still to run its course. We are not providing further commentary on top of what's happened to date."
Three people have been charged with drug trafficking following Friday's raid at Port Melbourne and another search at Geelong.
They include Thomas Windsor, 28, who was reportedly staying at Thompson's renovated warehouse at Port Melbourne.
A 31-year-old Lara man and a 22-year-old Mill Park woman were also charged.
Media reports suggest Windsor and the Lara man, named as Karl Holt, have bikie links in the Geelong area.
The trio were remanded in custody and are due to face court at Geelong at a later date.
Police said the arrests were part of an ongoing investigation into drug trafficking.
It's unclear how Thompson is allegedly connected.
His decorated AFL career includes three premierships during his playing days at Essendon and later coaching Geelong to two flags.
Thompson was an assistant coach at Essendon when the club's supplements saga came to light in 2013.
