Former LafargeHolcim Ltd. Chief Executive Officer Eric Olsen was placed under formal investigation and charged with funding terrorist groups as part of a French probe into the cement maker’s operations in war-torn Syria.

Olsen, who resigned from the company in April, was also charged late Thursday with putting someone else’s life in danger and placed under judicial supervision, said an official at the Paris prosecutor’s office who declined to be named in line with policy. A spokeswoman for LafargeHolcim declined to comment.

The French criminal inquiry focuses on the manufacturer’s now-shuttered operations in Syria, where Lafarge SA of France operated a cement factory before a merger with Swiss rival Holcim Ltd.
