As many as 2,730 children have been missing in Bihar since 2007, according to the data available with the police headquarters.
While 889 children had been missing in 2007, the figure was 975 and 866 in 2008 and 2009 respectively.
These children, either victims of child trafficking or abducted for ransom, have not returned home after the missing report was made to the police.
The percentage of missing children rescued or returned on their own has been declining, the data revealed.
While the recovery rate of missing children was 63 per cent in 2007, it was 60 per cent in 2008 and only 23 per cent in 2009.
Gauri Shankar Sharma, president of 'Akash Akhansha', an NGO working for children, described the state government's attitude towards the protection of children as "callous" and alleged that it had failed to constitute the State Child Rights Commission.
