A driver accused of being involved in the murder of a special constable told police he had nothing to do with the killing, a court has heard.
Nisha Patel-Nasri's husband is accused of organising the murder
Pc Ian McLone told the Old Bailey how Tony Emmanual said "I ain't murdered anyone" when he was arrested at his home seven months after the killing.
Nisha Patel-Nasri, 29, died when she was stabbed outside her house in Wembley, north-west London, in 2006.
Her husband Fadi Nasri, 34, and three other men from London deny murder.
Prosecutors allege Mr Nasri organised the killing in order to cash in on his wife's £350,000 life insurance.
Mr Emmanuel, 42, is accused of driving nightclub doorman Jason Jones to Mrs Patel-Nasri's home where she was stabbed in May.
Pc McLone told the court that later, while in a cell, Mr Emmanuel asked: "Who was it that was murdered?"
When he was told the victim was Mrs Patel-Nasri, Mr McLone said. "He stated 'I remember that, it was on Crimewatch, it will make headline news'."
Jurors were also shown pictures of blood stains left by the victim outside her home.
In a statement, forensic scientist Jennifer Guest described finding pools of blood in front of the house but none inside the home.
Mr Nasri, of Barnet, north London, Mr Leslie, 38, of Barnet, Mr Emmanuel, of East Ham, east London, and Mr Jones, 36, of Manor Park, east London, all deny murder.
The case continues.
