Russia's Kuzmichev put under formal investigation in France - source

French investigative judges on Wednesday put Russian tycoon Alexey Kuzmichev under formal investigation, a source at the financial prosecutor's office said.

Kuzmichev has been held for questioning since Monday and was put under formal investigation over allegations of laundering of tax evasion proceeds, money laundering and concealed work, the source said.

A lawyer for Kuzmichev declined to comment. (Writing by Ingrid Melander;editing by Diane Craft)
