Police will continue to question a 22 year-old man on Friday over the murder of a teenage schoolgirl whose body has still not been found.
Georgia Williams, 17, from Wellington, Shropshire, has not been seen since telling her parents she was going to see
friends on Sunday evening.
Police first arrested the 22 year-old man, also from Wellington, at a budget hotel in Glasgow for the alleged kidnap of the teenager and has since been returned to Telford.
But on Thursday police further arrested him on suspicion of murder.
50 detectives are hunting for Georgia Williams
Officers have been searching woodland and have taped off an area in a nature reserve about 17 miles from Wellington.
Uniformed officers and a police tent are currently at Brown Moss Nature Reserve, Shropshire.
The Sun has published CCTV images which are thought to capture the 22-year-old getting out of a van in a car park close to the hotel, the day before his arrest.
He is seen changing his shirt and spraying himself with deodorant.
Superintendent Nav Malik, Telford and Wrekin police commander, said yesterday: "I make it very clear, folks, that we have not found Georgia Williams at this moment in time.
"She remains elsewhere - we are not quite sure where.
"We are really, really keen to identify where she may be, her whereabouts and I urge the public to support us in trying to find out where she may be."
He added there were more than 50 detectives are working on the investigation.
Georgia has not been seen since telling her parents she was going to see friends at 7.30pm on Sunday.
Police said she had her mobile phone with her when she left, but the last calls and text messages were received from the device at about 8pm that night.
Forensics teams have searched a semi-detached house in Wellington where neighbours said a Jamie Reynolds lived with his parents.
Mr Malik said police were still keen to trace the movements of a silver Toyota Hiace 300 GS van which the man in custody had access to, which was seized in Glasgow.
The van, which has the number plate CV06 ASV, is believed to have left Wellington at about noon on Monday, travelling to Oswestry, Rhyl, Chester and Kendal before reaching Glasgow at about midday on Tuesday.
Mr Malik has previously said that Georgia's disappearance was "completely out of character".
He described the man in custody as a "friend" of the missing girl, but not her boyfriend.
Georgia, who is white, is described as 5ft 3in, slim with long dyed red hair, and was last seen wearing a waist-length black leather jacket over a white T-shirt which has a London bus motif on it.
She was also wearing black skinny jeans and flat, black suede slip-on shoes.
Police have been granted more time to question the 22-year-old man.
Detectives from the investigation team successfully made an application at Telford Magistrates' Court for a warrant of
further detention to continue to interview the suspect.
The warrant was granted for a 36-hour period which expires at 6.30am tomorrow.
