A CCTV image has been released of a commuter seen talking to a missing Penrith teenager.
Police are appealing to the lady who was chatting to 15-year-old Catalina Covaci at around 1.40pm in Manchester Piccadilly station on the day she went missing (19th December).
The teenager left her home in Penrith, with her six-month-old son Ricardo, after telling her guardians she was going into town.
She was seen at Penrith Train station on the morning she went missing, before taking a train to Manchester.
“CCTV investigation has revealed that Catalina spoke to a woman when she arrived in Manchester Piccadilly train station on the afternoon she went missing.
"It is incredibly important that we trace this witness to find out what Catalina said, whether she asked for help or whether she indicated where she may be going.
“We are into the fourth week of her disappearance and her family in Penrith are distressed and we need to ensure that we locate them both-quickly."
Police believe a 15 year old girl and her baby son who've been missing for a week could be in Oldham.
Police in Cumbria are now using Twitter to help with their investigation into the disappearance of a teenager and her baby son.
