Goldman Sachs has sold its embattled metal-storage unit to a Swiss company, a source familiar with the situation told CNBC.

A Geneva investment company, Reuben Brothers, has bought the unit, the source said.

Business practices at the Goldman metal unit, Metro, have been controversial, the source said. A senate panel accused Metro of manipulative practices in November.
