Police in the North are investigating separate overnight attacks on the homes of Protestant and Catholic clergymen in Co Antrim.
Several windows were smashed at the home of a Church of Ireland rector in Gleneavy, where a car windscreen was also broken.
The Rev Earl Storey, who was at home with his wife at the time, speculated that the attack might be linked to a book he wrote calling for the church to sever its ties with Orange Order marches.
Meanwhile, a smoke canister was thrown through the window of a Catholic parochial house on the Rock Road in Lisburn.
A flare canister was also found on the road outside the house.
