A Missouri man accused of trying to burn down a Planned Parenthood clinic in February now faces new charges.

Wesley Brian Kaster was originally charged March 4 with maliciously damaging a building owned by an organization that receives federal financial assistance. The Columbia Daily Tribune reports that a grand jury indictment on Wednesday replaced that charge with two new counts — using explosive material to maliciously damage federal property and malicious use of explosive materials.

An attorney for Kaster didn’t immediately respond to a message seeking comment.

The clinic in the central Missouri city of Columbia was empty when the pre-dawn fire broke out Feb. 10 . Authorities allege that the 42-year-old man broke the glass front door and threw in a “Molotov cocktail-type device.”
