Western Cape police could not comment on a report on Friday that Shrien Dewani, widower of murdered tourist Anni Dewani, was a suspect in the investigation.
“The case is already pending in court so we can't give anymore comments to the media,” spokesman Captain Frederick van Wyk said.
The Mail&Guardian reported that two “highly reliable” sources - who were not named - close to the investigation, said that Shrien was now a suspect in the murder of his Swedish wife in Cape Town.
The newspaper reported that investigations were taking place to persuade Dewani to return to South Africa voluntarily.
If he returned he would be charged and arrested.
Dewani flew out of Cape Town four days after his wife's body was found in Khayelitsha.
National Prosecuting Authority (NPA) spokesman in the Western Cape Eric Ntabazilila told Sapa on Friday that the NPA could not confirm the reports either.
“Police are doing the investigation so they are the people you need to speak to.
“The NPA does not have that information,” he said.
Dewani, 30, told a British newspaper earlier in the week that he rejected speculation that he was somehow involved in the incident earlier this month.
He told The Sun newspaper: “People who suggest this could not have seen us together.”
Anni Dewani's father had also spoken out in support of his daughter's husband.
Vinod Hindocha issued a statement on Monday, saying: “Further to recent reports in several newspapers I would like to state that my relationship with Shrien is a good one and I love him like a son.
“Whoever did this to my daughter are criminals who need to be caught and put behind bars.
“I have always supported Shrien and I will continue to do so throughout this horrendous ordeal.”
Anni, 28, and Shrien Dewani were married for two weeks when they were attacked by two armed men who hijacked their shuttle service vehicle near Gugulethu.
They were in Cape Town for their honeymoon. The couple was apparently returning from a dinner in Somerset West at the time of the attack.
The couple's driver on the night, Zola Tonga, 31, appeared in court on Monday in connection with the murder of Anni.
He and another man, Mzwamadoda Qwabe, 26, from Khayelitsha, appeared at the Wynberg Regional Court in Cape Town to face charges of murder and hijacking.
The police said Tonga was in the process of consulting the Director of Public Prosecutions about a possible plea bargain.
The first accused Xolile Mngeni, 23, was arrested last week Tuesday.
The case was adjourned to next Monday while further investigations are carried out. - Sapa
