Criminals in South Africa have recently sent an anti-crime website and social media group an anonymous message demanding a 5 BTC ransom ($19,200) to return a missing nine-year-old girl.

The admin of the anti-crime group Western Cape Gangwatch reportedly received the anonymous message via an email that claimed that, in order to find the missing nine-year-old, the group was to send 5 BTC to a specific address within 48 hours, or communication would cease.

Gangwatch, an organization that reportedly regularly cooperates with law enforcement agencies in the country, is said to have attempted to trace the email, but was unable to. Speaking to local news outlet IOL, a spokesperson for the group stated:

We are trying to track it via the Bitcoin code, but believe the email the person is using was probably created at an internet cafe, which automatically deletes it and there is no IP address available either.

By “Bitcoin code” the spokesperson was presumably referring to the bitcoin address, which is available to the public on the cryptocurrency’s blockchain. At press time, the address given by the kidnappers has only received 0.0168 BTC on December 31, an amount that was moved shortly after being received.

The funds were then moved to an address that has received over 120 BTC, but has moved all of it and has been reported as fraudulent two times. From that point on, the funds appear to have been sent to a cryptocurrency exchange.

Gangwatch’s spokesperson added that those responsible for the crime will “hopefully realize the family’s circumstances and realize they cannot keep the girl for a lengthy period.” Speaking to the publication Candice Sobotker, from the Western Cape Missing Persons unit, added that the search for the girl, Linathi Titshala, is still ongoing.

We are pooling all resources including doing a search again in the coming week.

Detailing what happened the girl’s grandmother, Nabantu Matanzima, noted she slept at her home after a party and was then sent to her house, which was two doors away, on December 16. Since then, she hasn’t been seen.

Cryptocurrency-related crime seemingly isn’t new in the country. Last year the country’s authorities were investigating an $80 million bitcoin Ponzi scheme that collapsed after its founder disappeared. Notably, a survey has found that 60% of South Africans were “not aware” of cryptocurrencies as of July of last year.
