An 86-year-old man is in a serious condition in hospital after being struck by a car in Armagh.
The collision, the latest incident in a grim week on Northern Ireland's roads, involved a grey Vauxhall Astra and happened in Gaol Square in the city at around 10.15am yesterday.
Inspector Philip Shepherd said: "The pedestrian is understood to be in a serious condition in hospital at present.
"We are keen to speak with witnesses to the collision. Investigators can be contacted on 101."
Meanwhile, tributes have been paid to a popular pensioner who has died after a 10-day fight for life in hospital following a road accident. Lizzie Moore (83) was hit by a car on Main Street in Portglenone last week.
She was rushed to hospital where she was treated for 10 days, but she succumbed to her injuries on Thursday.
Mrs Moore has been described as a popular local woman, often seen walking her little Terrier dog through the north Antrim village.
She had worked as a cleaner in a shop before retiring, and was widowed several years ago.
SDLP councillor Martin Kearney described Mrs Moore as "well known and liked".
"She was a popular person and a regular sight along the Main Street walking her little pet dog," he said.
"A very genuine, likeable lady.
"The local community is very sorry to hear she has passed on and she will be greatly missed."
Tributes were also paid to Mrs Moore on a Portglenone Facebook page.
A local hairdressing business posted that the pensioner and her wee dog were "very much part of our village".
Enda Clarke posted: "Sad to hear, lived beside Lizzy for many years, quiet wee lady".
Shirley McMaster said: "So sad to hear this news, Lizzie was a genuine wee lady, will be sadly missed end of an area rip little lady."
Ann Gordon wrote: "Lizzie was a remarkable lady, me and Lizzie had some laughs, she's going to be missed."
Meanwhile, the PSNI have said they still want to speak to the driver of a white van that was in the area at the time Mrs Moore was hit.
The collision, involving a Vauxhall Cavalier, happened on Main Street in Portglenone at around 10am on Tuesday, March 31.
