Kuala Lumpur, Jul 2 (IANS): A Malaysian Indian man and his Chinese wife have given up work to search for their two-year-old daughter who went missing about a month ago while on a walk with her mentally-ill grand-aunt.

G. Chandramohan, 24, and his wife Wong Lai Lan, 21, have said their daughter Nisha could have been found on the day she disappeared if a system such as the proposed Nationwide Urgent Response Information Network (NURIN) alert was in place.

Modelled after the Amber alert in the US, the NURIN alert was mooted in 2007 following the brutal murder and sexual assault of eight-year-old Nurin Jazlin Jazimin whose body was found in a sports bag.

However, the idea has yet to be implemented, The Star newspaper said Friday.

It has been almost a month since Nisha Chandramohan went missing in Pahang state.

The child went missing after her mentally-ill grand-aunt took her for a walk from her parent's home.

The grand-aunt was found wandering alone in the neighbourhood later that evening but Nisha was nowhere to be found.

Chandramohan was an odd-job worker and Wong was a clerk before they set out on the mission to look for Nisha.

"We set out early in the morning and come back late. We are sure someone is keeping her. We have to keep looking and show people Nisha's picture," said Chandramohan.
