A pedestrian has died after being struck by a car in County Durham.
Matthew Carty was hit on the A1052 at the junction with Woodstone Village at 02:15 GMT on Sunday by a vehicle travelling from Bournmoor towards Fencehouses.
The 36-year-old, of Lambton, Washington, died in hospital.
Two people were arrested on suspicion of causing death by dangerous driving, but one of them, a 36-year-old woman was later released under investigation.
Police said the other, a 39-year-old man, was taken to hospital while inquiries continued.
Mr Carty worked as a postman in the Houghton-le-Spring and Sunderland areas.
In a statement, his family said: "Matty was kind-hearted, always smiling, always trying to cheer people up.
"He would often be singing - a lot of the time he sang silly songs and would often be singing at work.
"He was just amazing. We will miss him so much."
