A JURY has heard how one of Will Blencowe's co-defendants described him as an "idiot" after he was arrested.
Bradley Jones, who denies perverting the course of justice, allegedly made the comment after he was taken into custody in on February 15 this year.
The 21-year-old was arrested on suspicion of assisting an offender after Blencowe fatally stabbed Connor Tremble on February 13.
The prosecution alleges Blencowe killed the 17-year-old in a jealous rage because Connor was seeing his ex-girlfriend Amiee Harrison.
Blencowe, of Oxford Road, Banbury, admits stabbing the teenager but denies murder, claiming he was acting in self defence and was suffering from a mental condition.
This afternoon acting Detective Constable Richard Lewis described comments made by Jones after he was arrested and while he was in the back of a police car.
He said: "(Jones) said 'Will's an idiot, he's gone downhill'.
The officer added: "He was asking 'is (Connor) alright? I heard there was another boy in the room with him'."
DC Lewis said he told Jones not to say anything until he had spoken to a lawyer.
The jury also heard when Blencowe was told he was under arrest on suspicion of attempted murder, he repeated "attempted murder" and giggled.
PC Anita Dyer, who heard the remark after the defendant was found in a Stratford-upon-Avon guesthouse, said she thought it was "inappropriate" given the circumstances.
Jones, 21, of New Road, Bledington, and Grant Clemens, 23, of Stockwells, Moreton-in-Marsh, are also on trial and both deny perverting the course of justice.
The trial continues.
