They were reported missing on Tuesday 6 March.
Police looking for two missing Batley schoolgirls say they're still yet to find them.
Bernadett and Szimonetta Berki, who are 12 and 11, diappeared on Tuesday 6th March.
It's now believed they could be with their three-year-old niece - Leonetta Bogdan.
The children lived in the Chapel Fold area of Batley, but have extensive links and extended family across Huddersfield. It is also thought they have links to the Leicester area. All three are known to have strong links to the Hungarian community.
Detective Chief Inspector Fiona Gaffney of Kirklees District Police, said: “We have been carrying out extensive enquiries to trace all three children since they were reported missing including press appeals. Most of the work has been behind the scenes, however, as we strongly believe the three girls are with family members. We do not believe any third party is involved.
“Work has included enquiries and working with partner agencies including those in Hungary.
“We are however becoming increasingly concerned for their welfare as we have been unable to find them and are now calling on members of the public, particularly members of the Hungarian community, to come forward and help us find these girls as we need to locate them and ensure they are OK.”
