Church goers attending a service in Magherafelt had fireworks throw at them on Remembrance Sunday.
The incident happened yesterday evening.
There were also attempts made to damage police vehicles and assault officers.
Police say it was a ‘shameful end’ to Remembrance Sunday in the town.
Three people were arrested, one of whom was charged with a view to a court appearance.
“Last night saw an unfortunate and shameful end to Remembrance Sunday in Magherafelt – a band of thoughtless individuals decided that on the 11th of November of all days it would be a poignant tribute to the sacrifices made for our freedoms, to throw fireworks at the people of Magherafelt attending a church service. Never mind the obvious risk to property and people’s safety the sheer disrespect and thoughtlessness is galling,” said a spokesperson.
“It’s a bitterly disappointing black mark on an otherwise respectfully celebrated day, caused by the smallest minority of people – if that’s your idea of a laugh on a Sunday evening then we don’t really know what to say other than you’ll be seeing a lot of us,” added the spokesperson.
