The lead detective in the Oscar Pistorius murder case is himself facing attempted murder charges for firing on a minibus full of passengers, South African police said as prosecutors argued in court to deny the athlete bail.
Hilton Botha, who took the stand against Pistorius at the Paralympic and Olympic track star's bail hearing earlier this week, is due to appear before a judge in May over the 2011 shooting, police spokesman Brigadier Neville Malila said.
"Botha and two other policemen allegedly tried to stop a minibus taxi with seven people. They fired shots," Malila told Reuters.
It was unclear why the charges were reinstated against Botha, or how the latest twist in Pistorius's sensational four-day bail hearing will affect the athlete's chances of securing release from custody pending his trial.
At the time of the taxi bus shooting, Botha - a detective with 24 years on the force - was chasing a man accused of murdering a woman and disposing of her dismembered body down a drain, local media said.
The charges against him were provisionally withdrawn but reinstated on February 4 - 10 days before the shooting of 29-year-old model and law graduate Reeva Steenkamp in a locked toilet at Pistorius's Pretoria home, the National Prosecuting Authority (NPA) said.
"The decision to reinstate was taken on February 4, way before the issue of Pistorius came to light or the murder of Reeva was committed," NPA spokesman Medupe Simasiku told Reuters. "It's completely unrelated to this trial."
Malila said now that the court had decided to charge Botha, there would be an internal disciplinary investigation which would decide whether to keep him on the case: "At this stage there are no plans to take him off the Pistorius case."
Pistorius, a double amputee dubbed "Blade Runner" because of his carbon fibre racing blades, faces life in prison if convicted of the premeditated murder of Steenkamp in the early hours of Valentine's Day.
JUSTICE ON TRIAL?
The revelation about Botha capped a troubling 24 hours for South Africa's prosecution service.
Under cross-examination at the bail hearing on Wednesday, the lead detective was accused of contaminating the crime scene in Pistorius's house and had to backtrack on details such as the distance of witnesses from the athlete's home.
Grilled by lead defence counsel Barry Roux, he also had to concede that Pistorius's version of events - that he fired into the toilet door in a blind panic thinking an intruder was lurking behind it - was plausible.
The bail hearing resumed on Thursday with prosecutors immediately admitting they had only just found out about the charges hanging over Botha.
Pressing home the defence's advantage to argue for Pistorius's release, Roux said: "The poor quality of evidence presented by the chief investigating officer exposed disastrous shortcomings in the state's case."
The 26-year-old runner denies murder and was more composed in court after repeatedly breaking down in previous hearings.
His uncle, Arnold Pistorius, said his nephew was eating again after consuming nothing for six days and had spent much of his time in police custody reading the Bible.
SOUTH AFRICA AGOG
The proceedings have gripped South Africans, who have become self-appointed instant experts on the finer points of police forensics and the ins and outs of the criminal justice process.
As public opinion has swayed back and forth, schoolchildren have come to blows in playgrounds over the athlete's innocence or guilt, and on Thursday "Hilton Botha" was a top-trending topic on Twitter in South Africa.
"We talk about the case every day. It's all over the news. You can't ignore it," said Happy Ngwenya, a taxi driver waiting for rides in Johannesburg's Sandton financial district.
"He must face his music but the thing is, here in South Africa, criminals have so many rights."
With massive international media interest in the case against a global celebrity, many South Africans feel the apparent hiccups on the part of the state prosecution were hurting the country's image in the eyes of the world.
"Bring someone from outside to sort out this mess," said businessman Godfrey Baloyi. "The whole justice system needs an overhaul."
NIKE SUSPENDS CONTRACT
Meanwhile, Nike has suspended its contract with Pistorius.
"We believe Oscar Pistorius should be afforded due process and we will continue to monitor the situation closely," Nike said in a brief statement posted on its website.
On Monday, eyewear maker Oakley suspended its contract with Pistorius.
Nike dropped Lance Armstrong in October 2012, citing insurmountable evidence that he participated in doping and misled the company about those activities for more than a decade.
But the company stood by Tiger Woods after he admitted to infidelities and went to rehab for sex addiction.
