Connor Tremble: Oxford stabbing victim's mother pays tribute
The mother of a teenager who died following a stabbing in Oxford has said her son's death has "ripped her heart to pieces".
Connor Tremble, 17, died at the John Radcliffe Hospital on Saturday after a decision was made to switch off his life support machine.
Police have been searching drains and bins around south Oxford for evidence.
They have been given an extra 36 hours to question a 20-year-old man from Banbury on suspicion of murder.
A post-mortem examination failed to establish the cause of Connor's death.
Lisa Tremble said: "Connor was a much-loved son, big brother, nephew and grandson. His death has ripped my heart into pieces and I feel I have been robbed of something priceless.
"I want justice for Connor and to appeal for anybody with information regarding his death to come forward.
"I urge you to think about the value and delicacy of life."
Connor's father, Martin Smith, said the teenager would "hold a place in my heart until the day that I die".
He said: "Wherever he is, may he have found peace and comfort."
The stabbing happened in Fairacres Road at about 18:45 GMT on Thursday.
Floral tributes have been left at the building where Connor lived.
Police arrested the suspect in Stratford-upon-Avon on Friday. He can be held until Tuesday morning.
A 21-year-old man from Birmingham, arrested on suspicion of assisting an offender, has been released without charge.
