A man has been arrested following Northern Ireland's first fatal car crash of 2016.
Fashion store co-owner Norma Diffley (75) died in the two-vehicle collision on the main Belfast-Bangor road on Monday.
The Groomsport woman ran a Donaghadee boutique called Re-Creations.
The PSNI said yesterday that officers investigating the fatal crash on the A2 dual carriageway had arrested a 33-year-old man on suspicion of dangerous driving causing death.
On Wednesday he was released on bail pending further enquiries.
The collision between a blue Suzuki Jimny 4x4 and a blue Volkswagen Tiguan happened at around 2.10pm close to the notorious Devil's Elbow bend at Carney Hill.
Mrs Diffley, a great-grandmother, is survived by daughters Lisa Bell and Lynn Stevenson.
Her second-hand designer fashion store, which she ran with Ms Stevenson, opened in 2007.
Mrs Diffley also lived in London for 16 years and worked at the House of Lords as a secretary to the Clerk of Sound Archives.
Known to friends as 'Nornie', Mrs Diffley was involved in Groomsport's Remembrance Sunday parade and attended Groomsport Church of Ireland, where she had run the Sunday School for many years.
Police have appealed for anyone who was travelling in the area at the time and witnessed the collision or has any information to contact the Collision Investigation Unit at Sprucefield on 101.
