A suspect is in custody as authorities investigate a weekend fire that damaged Mississippi’s largest synagogue, which has been attacked before.

The fire broke out around 3 a.m. Saturday at Beth Israel Congregation, the only synagogue in Jackson, the state capital. Video surveillance footage shows a man splashing liquid along a wall onto a couch in the lobby.

Investigators said the blaze burned the lobby, the library, and the offices. Soot and smoke damaged the rest of the building, including the sanctuary. The building also houses the offices of the Institute of Southern Jewish Life.
