Gurpreet further told the investigators he had given her a marriage proposal, which she turned down. He also said that when he came to know she was having an affair with someone else, he planned to kill her, police said.

He called her to India and strangled her to death, Gurpreet told the investigators.

"But there are certain dots which are yet to be connected and Gurpreet is not revealing everything it seems," a police official said.

During interrogations, he first said two more people were involved in killing Berger. But later, he retracted his statement. The police has so far not found anyone else's role in the murder, an officer said.

Gurpreet is in a four-day police custody and is being interrogated.

The postmortem examination of the body is yet to be conducted as the deceased's family members could not be contacted. The police has tried tried to approach her family through the Switzerland embassy.

On Sunday, the embassy officials met the Delhi Police officers to know about the details of the case.

The police also said they were investigating the case from multiple angles, including human trafficking and money trail as Rs 2.10 crore cash was recovered from Gurpreet's house in Janakpuri.

Gupreet's father runs astrology and gems business and the family owns multiple properties.

Transactions of a large amount were also done in his bank accounts. The Delhi Police's Economic Offences Wing (EOW) and the Income Tax department have been informed to track the money trails.

The police has seized three mobile phones from his possession. According to Gurpreet, one of the phones belonged to Nina, while two belonged to him.

The data recovered from his mobile phone indicates that he might be involved in a network of human trafficking. Is being verified whether the woman too was a part of that network, police said.

Several phone numbers of foreign women were also found in his mobile phone.

Police said the car used in dumping the body was bought by the accused earlier this month from a woman, who is suspected to be a part of this network.
