A WOMAN is expected to be charged with attempting to drown her two children in a rural area near the New South Wales-Victoria border.
NSW police said on Friday they were expected to apply for the woman's extradition from Victoria
A nine-year-old boy was found with serious dog bite injuries on the banks of the Murray River in Moama about 7pm on Thursday.
He was taken to Echuca Hospital to be treated before he was taken to Melbourne.
His five-year-old brother is believed to be missing in the river. Police divers and other emergency services have been searching for the boy's body since 8am after calling off the search late on Thursday night.
"About 10pm, a 27-year-old woman, who is the children's mother, presented herself to police at Echuca in Victoria," NSW Police said in a statement.
"She has since been released and is assisting detectives from Deniliquin Local Area Command with their inquiries. It is expected NSW Police will be applying for her extradition."
ABC reported the woman was expected to be charged with murder and attempted murder.
Superintendent Paul Condon said the dog who bit the boy belonged to a local family.
"Contrary to rumours, the dog was not set on the child. This has been an extremely traumatic scene for all the first responders involved and welfare support is being offered.''
