Steenkamp is said to have had a close friendship with the 24-year-old rugby player, who was also a pal of Oscar Pistorius.

Speculation about the pair’s relationship started on Twitter, with a message from Nelson Mandela’s assistant Zelda la Grange saying “Have you heard ­rumours about a rugby player alleged to be involved somehow? We all have,” reported The Daily Mirror.

As police check through personal messages on phones and computers, rumours have surfaced that the tragic Valentine’s Day death of Steenkamp could be linked to her relationship with Hougaard.

However, Hougaard has denied he had anything to do with the incident. The rugby player’s agent Lorinda Voges said “Our client will not answer any questions regarding Reeva Steenkemp or Oscar Pistorius at this stage as this is still an ongoing investigation and this whole sad ordeal has got nothing to do with him.”

The latest alleged revelations have led to speculation about Pistorius’ use of steroid drugs, leading to “roid rage”. The Sun suggested that the athlete may have been in possession of the performance-enhancing drugs, according to a source, “Steroid drugs were found at Pistorius’s home together with evidence of heavy drinking. That’s why police have specifically ordered that he be tested for steroids.”
