Police in Malaysia searching for missing teenager Nora Quoirin have set up a hotline in the hope of getting new information on her disappearance.
They say Nora, who was born with brain disorder holoprosencephaly needs help with many aspects of everyday life. She has been vulnerable since the day she was born.
In a video broadcast on local media, she said: "We want to say thank you to each and every one of you".
Her family offered a 50,000 ringgit ($11,900) reward, donated by a Belfast business, for information that could lead to her return, said The Lucie Blackman Trust, a charity that supports the families of British people missing overseas.
The reward money was donated anonymously by a Belfast-based businessman as the search for the young girl, who has serious learning difficulties, expanded to some 350 people and has now drafted in officers from Scotland Yard, France, Ireland and Interpol.
British, Irish and French police are in Malaysia to assist with the search, said state deputy police chief Che Zakaria Othman, declining to comment on their role in the investigation.
The teenager's aunt set up an online fundraising page in the aftermath of her disappearance, which has so far collected more than £89,000.
She and her family, who arrived in Malaysia from London on Aug 3 for a two-week holiday, checked into eco-resort The Dusun in the dense tropical forest in Negeri Sembilan.More news: Albon replaces Gasly at Red Bull from Spa

Nora's parents discovered her missing from her bed with the room windows wide open on the morning of August 4, after the family had arrived in the southeast Asian nation for the "holiday of a lifetime".
Some 300 Malaysian searchers aided by drones and sniffer dogs are scouring the forest area near the resort, playing recordings of Nora's mother calling out to her.
The family have said they remain hopeful after police leading the investigation refused to rule out a "criminal element".
Investigators have questioned 20 people and said a forensic team was analyzing fingerprints found in the cottage where the girl went missing. "Most important now, the child will be released".
The mother Meabh Quoirin, in a short speech, held back tears as her husband Sebastien stood beside her, rubbing her arm.
"We are committed to finding her", he told reporters.
