New leads after Kent murder victim's family makes plea
Detectives hunting the killer of a man from Kent said they have had a good response to a televised appeal.
Father-of-two Adrian Milner was walking home from the pub with a friend on 28 December last year when he was punched by a stranger.
The 48-year-old hit his head on the ground in Church Road, Sittingbourne, and died in hospital 12 days later.
Police said they received 22 calls following BBC1's Crimewatch appeal on Thursday evening.
Jog people's memories
CCTV footage has also been released of a man detectives want to speak to in connection with the incident.
The image shows a man in a white cap, holding a white carrier bag, walking behind Mr Milner before the attack.
The programme featured interviews with Mr Milner's partner, Gemma Stuttard and one of his sons, Josh, 20.
His brother, Duncan, said he hoped the programme would jog people's memories.
He said: "Bringing his killer to justice would help us come to terms with Ada's death."
Det Sgt Richard Le Jeune, of the Kent and Essex serious crime directorate, also appeared on Crimewatch to appeal for the public's help with information.
