Knife seized as family grieves for 'road rage murder' victim Donald Lock
British police have seized a knife and sent it for forensic examination as they continue to question a man over the alleged road rage murder of a great-grandfather.
Donald Lock, 79, was knifed repeatedly after he got out of his car following a minor crash on the A24 at Findon, near Worthing in West Sussex.
Mr Lock had been attending a social gathering of Worthing Excelsior Cycling Club, its secretary Adrian Palmer said.
Mr Lock was believed to have been on his way home when he crashed into the back of another car, got out of his vehicle and was stabbed multiple times.
Married for 55 years, Mr Lock died at the scene at around 8.40pm on Thursday.
His family said he had recently been given the all-clear from cancer and was due to become a great grandfather for the sixth time.

Realives said in a statement: “(Don) still holds the club record for the 24-hour time trial having remained unbeaten for 44 years. He was full of energy having recently been given the all-clear from cancer.
“Not only was he passionate about cycling but he had also been supporting Brighton and Hove Albion since the 1940s and was a season ticket holder.
“He loved travelling the world with his wife Maureen and he adored his family. He and Maureen had just celebrated their 55th wedding anniversary.”
Mr Lock, known as Don, leaves son Andy, daughter Sandra, four grandchildren, and five great-grandchildren, with the sixth great-grandchild due later this year. He had lived in Worthing for 55 years.
A 34-year-old local man is being questioned on suspicion of murder after he was arrested by armed officers some 18 hours after the incident.
