Mokbel family is downsizing now the money that once rolled through the front door is gone.

 
Although there's a Mercedes-Benz still parked in the driveway, the little hatch model with P-plates is a far cry from the black gangster Merc of choice Tony bragged about at the peak of his life of crime in the illicit drug market.

A Mokbel relative was in no mood to talk at the family home in Brunswick, where deals were often done just walking distance from the cafes on Sydney Rd where "Fat Tony" would make his presence known.

"We're not interested. I'm not interested. Which part don't you understand?" the relative said.

"It's not my problem ... we've got nothing to say."

It's believed the family is caring for Laura Mokbel, who has previously staunchly defended Tony amid the Purana Taskforce investigations.

But the family woes do not extend only to Tony.

Older brother Horty Mokbel has been charged with bashing an inmate in Castlemaine's Loddon Prison.

Horty, along with three co-accused, all face counts of intentionally causing injury, assault in company, assault by kicking and unlawful assault following an incident on March 29.

Along with his co-accused, Horty was transferred to where brother, Tony, was jailed at Barwon Prison earlier this month.
