Relatives of a man murdered in a brutal and unprovoked single-punch attack have made an emotional plea for witnesses to come forward.

Adrian Milner was hit in the face as he walked home along Church Road in Murston, Sittingbourne.

This single blow caused Mr Milner to fall to the floor and hit the back of his head.

He died 12 days later in a London hospital.

The attack happened three days after Christmas just before 7.53pm on December 28.

Now Adrian’s family and friends are calling for help to find the man who attacked him.

His brother Duncan said: "We just want justice for Ada so he can rest in peace.

"We want the man responsible for the attack to come forward, as we have not been able to move on from this, knowing that the offender is still out there and able to continue his life as if nothing has happened.

"Adrian’s death has brought much sorrow and heartache to the whole family and his absence has left a big hole in our lives.

"We love him and miss him so much."

Police have releasing new CCTV images of men they wish to speak to who could assist the investigation.

Detective Inspector Lee Whitehead, of the Kent and Essex Serious Crime Directorate’s Major Crime Unit, said: "Mr Milner and his friend Michael Coomber had been for a drink in the New Inn that evening.

"They were walking home along Church Road when a third man punched Mr Milner in the face.

"At this stage we believe it to be a completely unprovoked attack.

"We continue to analyse CCTV footage of the evening, not just in Church Road but further afield, which is why we are releasing these new images in a bid to bring forward new key witnesses who could help us reveal the identity of the offender."

He added: "I would urge people to study the images closely to see if they recognise those in the photos.

"Alternatively, those pictured may wish to contact us themselves to rule themselves out of the enquiry."

A 35-year-old man bailed in connection with the investigation has been released without charge.

A 30-year-old Sittingbourne man remains on bail.

Anyone with information is asked to contact Kent and Essex Serious Crime Directorate on 01622 654852 or Crimestoppers on 0800 555111.
