THREE young girls have gone missing from their home in Elland.
It is believed the children, one of whom is just two, could be in Huddersfield.
Details of their disappearance were revealed today as an appeal for help was made.
The children disappeared almost two weeks ago on Thursday, February 26.
Police believe Amanda Jeffrey, aged 13 (pictured, above), Isha Dawkins, nine (pictured, below), and Portia Dawkins, two, could have made their way to the Huddersfield area.
Social workers from Calderdale Council today appealed for the public's help to find the youngsters.
Glenys Allin, head of children's services in health and social care at Calderdale Council, said: "We believe there will be people who know the children's whereabouts."
She said the youngsters had recently been living in the Elland area after moving from Huddersfield.
Both the older girls were born in Jamaica, while Portia was born in Huddersfield.
While the hope is that they remain in Yorkshire, it is feared the three could have travelled as far afield as London.
They might even attempt to leave the country.
Mrs Allin said the girls' family were under an enormous amount of stress while the council was becoming increasingly worried about the youngsters' wellbeing.
Karen Hayward, a council spokeswoman, added her voice to the plea for their safe return.
"We are appealing to the public, if they think they know where the children are, to contact us."
She added: "We think it is likely somebody does know where they are - a neighbour, a relative, a friend of the family."
Amanda is also known as Shannon while Isha has used the name Lisa Dawkins.
Amanda is about 5ft 4in tall with short hair sometimes worn in braids.
Isha is 4ft tall. She has a brother and mother still living in Jamaica.
Portia is of mixed race and just 3ft tall.
She is a talkative child who chats readily to adults and enjoys attention.
Anyone who has information on the girls should contact Halifax police on 01422 337059 or Calderdale Social Services on 01422 393884 or 01422 365101.
