Model, 14, who died in China 'may have been deliberately poisoned' - reports

'The origin of the poison has not been established yet,' reported Life. 

'Vlada could have been bitten by a mortally poisonous insect, she could have eaten something, or she could have been deliberately poisoned.'

Reports say additional tests will now take place. 

A criminal case was opened into her death last month by the Russian Investigative Committee. 

There was criticism that she had been allowed to miss school and work in China without medical insurance. 

She died in China following a gruelling 13-hour modelling assignment.

The case has raised concerns over the "exploitation" of underage Russian models desperate for glittering catwalks careers.

When she died, there were reports she had contracted meningitis. 

The official Chinese versions was that she died from septicaemia  "with multiple visceral organs damaged, liver dysfunction and renal insufficiency".
