A man arrested in connection with the disappearance of a teenage mother has been released without charge.
Natalie Putt went missing on 1 September last year
West Midlands Police said the 18-year-old was arrested on Thursday by officers attempting to trace 17-year-old Natalie Putt.
Miss Putt disappeared from her home in Upper Gornal, in September last year, 11 weeks after giving birth.
A police spokesman said the man was released without charge on Friday and inquiries were continuing.
Further forensic examinations were being carried out at Miss Putt's home, the spokesman said.
The Nottinghamshire force's underwater search team was assisting with the inquiry, the spokesman added.
The teenager disappeared after saying she was going to the shops near her home in Thornleigh, near Dudley, on 1 September.
She took no personal possessions and left behind her three-month-old baby son Rhys.
Rhys is being cared for by Natalie's father and stepmother.
