'Waste of life'
Mike Fuller, Chief Constable of Kent Police, visited the scene of the stabbing on Wednesday afternoon.
"Already a picture is starting to come into place about what happened," he said.
"It's such a waste of a life. It's so wrong. They won't get away with it. I'm very confident of that."
He said community officers were working closely with people in the area and liaising with ethnic support groups.
Christopher, also known as Christian Roberts, was attacked in Sheerness High Street.
A man arrested shortly after the attack has been bailed pending further inquiries.
Detectives are continuing to question a third man, who was arrested in the Maidstone area on Sunday evening.
