Yasmin Chaudhry told police she was video-chatting with her British love-interest Ammaz Qureshi and that he urged her to “discipline” little Hunaina.
The girl drowned as a result, Oslo police said.
Chaudhry, 26, who initially told cops her daughter’s death in October 2010 was an accident, has been charged with unintentional murder and is in jail awaiting trial.
Her 5-year-old son has been removed from her home.
Qureshi, 33, conceded in interviews with cops that dunking the toddler in cold water was a scheme he and Chaudhry cooked up together, prosecutor Kristin Rusdel said.
“He confirmed he witnessed it on Skype but not that he instructed her to do it,” Rusdel said.
No charges or formal extradition requests have been made for Quereshi, who is a British citizen and began an internet relationship with Chaudhry after meeting her just once.
Chaudhry’s lawyer said his client is innocent and that Qureshi should face charges.
“I want to express that we want Mr. Qureshi to be extradited from U.K. and face trial in Norway,” Geir Hovland said.
If convicted, Chaudhry faces up to eight years in prison.
