The teenage son of high-profile dissident republican Colin Duffy has been killed in a car crash.
Co Armagh man Seanna Duffy (19) died in the smash involving a car and a lorry on the Saintfield Road in Lisburn yesterday.
It's understood a woman who was also in the car was one of two people taken to hospital for treatment.
The NI Ambulance Service (NIAS) said it was called to the crash at 10.25am.
"A rapid response paramedic, three emergency crews and an ambulance hazard area response team officer were called to the scene," the NIAS said.
"The charity Air Ambulance HEMS team was also scrambled to the incident.
"Following initial assessment and treatment at the scene, two patients were taken to the Royal Victoria Hospital in Belfast."
The PSNI later confirmed that a 19-year-old male died in the collision which involved a silver Ford Focus car and a tanker lorry.
"Police would appeal to anyone who was travelling on the Saintfield Road, in either the direction of Temple or coming from the Temple area and may have witnessed this incident which involved a silver Ford Focus and a tanker lorry, or anyone who has dash-cam footage that would assist in our enquiries, to contact the PSNI collision investigation unit on the non-emergency number 101," the PSNI said.
Motorists were requested to avoid the area as investigators examined the cause of the crash.
A funeral notice from the family said that the Lurgan man had died "suddenly as result of accident".
It described him as "Seanna, dearly beloved son of Colin and Martine, Lurgan RIP, and much loved brother of Caitriona, Aimee, Sinead, Oisin and Fionntan and loving uncle to Braeden and Séanna.
"Sacred Heart of Jesus have mercy on his soul.
"Very deeply regretted by his loving father, mother, sisters, brothers, nephews and entire family circle."
Heartbroken friends of the teenager took to social media to share their grief.
Pal Diarmuid Scullion wrote: "RIP Seanna Duffy. Can't believe I'm writing this, absolutely heartbroken.
"Such a gentleman. So happy to call you my friend and that will never change... rest easy mo chara..."
In April, the Duffy family home in Lurgan was attacked. Pictures showed broken glass in a window at the front of the property.
Dissident group Saoradh described the incident as a "reckless attack."
No one was injured.
In recent months, Seanna's father Colin Duffy (50) has been on trial on a series terrorism-related charges, including preparing and directing terrorism, and membership or professing to be a member of the IRA.
He denies the charges.
In the dock with him and facing similar charges were Henry Fitzsimons (51) and Alex McCrory (57).
Fitzsimons and McCrory have also been charged with - and deny - attempting to murder police and possessing the two AK47 assault rifles and ammunition used in the attack.
