Missing Jayden Parkinson: Two arrested in murder probe
Two people have been arrested on suspicion of murdering a missing teenage girl from Oxford.
Jayden Parkinson, 17, was last seen in the Iffley Road area of the city on 3 December after leaving a youth hostel. She did not return home as planned.
A 22-year-old man from Reading and 17-year-old boy are being held in custody as the search for Jayden continues.
Thames Valley Police said the 22-year-old was "in a relationship" with the girl.
Officers were on Saturday granted a further 12 hours, until 16:30 GMT, to question him.
The 17-year-old boy was arrested after attending a police station in Oxfordshire earlier.'Shocked and concerned'
Jayden, who until last month was living in Didcot, Oxfordshire, with her mother, is described as white and slim, with shoulder-length dark brown hair and brown eyes.
She recently became homeless and had been living at a hostel in Oxford called 1 Foot Forward.
Police have issued a CCTV image of her leaving Didcot Parkway railway station at 16:27 GMT on 3 December. She had earlier caught a train from Oxford.
About 50 detectives are involved in the search, which is being concentrated on a rural area between the village of Upton and Didcot, around a disused railway line.
Det Ch Supt Andy Murray, who is leading the investigation, said officers were keen to hear from anyone who was in the area between the evening of the 8 December and the morning of 9 December.
"There was an incident there on the Sunday night leading into the Monday morning," he said.
"If you saw anything suspicious, please call us; we would like to hear from you.
"Information we have received has led us to concentrate our search in that area."
Det Ch Supt Murray stressed the investigation was still "a live missing persons inquiry".
"As time goes on, we're becoming increasingly concerned for her welfare.
"Jayden's family are being seen by a family liaison officer and are understandably shocked and concerned.
"They want their daughter home safe and well."
