PETALING JAYA: The family of a Dutch model who fell from the 20th floor of an apartment last week has expressed doubt that her death was an accident.

Ivana Esther Robert Smit, 19, was found naked on the balcony on the sixth floor of the apartment in Jalan Dang Wangi last Thursday (Dec 7).

Dang Wangi OCPD Asst Comm Shaharuddin Abdullah said police have classified the case as sudden death.

However Ivana's father, Marcel, told Dutch NL Times in The Netherlands that he believed his daughter was pushed from the apartment, where Ivana was staying with an American man and his Kazakhstan wife.

He claimed there were bruises on his daughter's neck, showing that someone had grabbed her.

RTL Nieuws reported that police told Marcel that she fell at about 10am from the apartment.

“Very strange that the American couple did nothing from 10am to 3pm. Ivana's belongings were still in their apartment. The police tell me that the statements of the Americans are the same.

“My daughter can no longer contradict them," Marcel said.

He said the neighbours heard shouting and arguments in the American couple's room.

“We want justice,” he told the newspaper.

According to newspaper AD, Ivana had called her boyfriend around 7.25am last Thursday and told him that she was with an American couple after a night out.

NL Times said the Dutch Embassy in Malaysia had asked Interpol to look into Ivana's death.

Ivana was the second runner-up in the Malaysia Supermodel Search 2014, when she was just 15-years-old.
