Officers do not believe the stabbing was a random attack, and Thames Valley Police have been questioning the man in custody over the weekend.

Connor was originally from Banbury, but had recently moved to Oxford, it is understood.

His mother Lisa Tremble said in a statement: “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.”

Nearly 2,500 people joined a Facebook page over the weekend called “Justice for Connor Tremble” in tribute to the teenager.

Connor’s father Martin Smith, described him as a “charming, happy-go-lucky boy”.

“Wherever he is, may he have found peace and comfort. He will be greatly missed,” he said.

Thames Valley Police have been given more time to question the 20-year-old man arrested in Stratford and can hold him in custody until tomorrow (Tuesday).

A second man, aged 21 from Birmingham, arrested on suspicion of assisting the offender has been released from police custody with no further action.

The police are continuing to investigate the murder. Anyone with any information should call the non-emergency number 101.
