Nora has not been seen for seven days after she vanished from the family’s cottage at the exclusive Dusun Rainforest Resort near Seremban, Malaysia.
The 15-year-old struggles to walk, balance and look after herself as she is disabled.
Cops from the Bukit Aman – equivalent to the FBI – are checking records of known paedophiles and other criminals in the area.
Detectives are also searching the homes of staff working at the resort, and quizzed the taxi driver who took them from Kuala Lumpur Airport.
Her family have issued a desperate plea to find her as she was last seen at 8am last Sunday.
“We are very worried about Nora’s welfare and do not know how long she can survive”
Mohamad Bin Mat Yusof
Police chief Mohamad Bin Mat Yusof said: “We are very worried about Nora’s welfare and do not know how long she can survive.
“We have no sign of her and no leads.”
Detectives believe Nora left the room through an aluminium-framed ground floor window.
Her family fear she was abducted, because her disability means she “does not go anywhere alone”.
Nora has holoprosencephaly, a condition which means her brain is smaller then average.
Police have admitted it is possible the window was opened from the outside and are now checking for fingerprints.
Detectives however refuse to call it an “abduction” case – insisting it remains a missing persons case.
Rescuers are combing the rainforest, including playing her mum Meabh’s voice on a speaker through the jungle.
Comparisons have already been drawn with the vanishing the Madeleine McCann, the three-year-old who went missing from her families holiday rental in Praia De Luz.
Meabh broke down in tears yesterday as she thanks search and rescue teams in the jungle.
The regular worshipper at a catholic church in Balham, south-west London, she said she is praying for Nora’s return.
Her husband Sebastian comforted her as she issued a further emotional plea.
The team of 317 men and women continue to search for Nora day and night.
Meabh said: “We see you’re working so hard and are also praying with us and being with us. We want to say thank you to each and every one of you.
“It means the world to us and we are so grateful for everything that you are doing for us.
“Everyone here, and everyone who is helping who is not here, we are extremely impressed with the effort, your expertise, your dedication.”
Her voice breaking, she said: “We hope you find Nora.”
The family are still staying in the property at the eco-resort, which is being guarded by police.
Relatives have jetted in to be with Nora’s parents and help with the massive search.
Police and volunteers will today continue searching the area around the cottage – even though it is a Muslim holiday in Malaysia.
Nine drones and a helicopter have been deployed to find Nora, and they are also combing through phone data and email traffic to find who was in the area when she vanished last week.
