PRETORIA, South Africa — Prosecutors reinstated attempted murder charges against a policeman leading the murder investigation into world-famous athlete Oscar Pistorius, in the latest twist in a case that has captivated South Africa and threatens to bring down a national idol.

The announcement that detective Hilton Botha faces reinstated charges in connection with a 2011 shooting incident came a day after he testified for the prosecution in Pistorius' bail hearing, and by all accounts bungled his appearance. He acknowledged Wednesday that nothing in Pistorius' account of the fatal Valentine's Day shooting of his girlfriend contradicted what police had discovered.

The spokeswoman for the nation's prosecutors urged that Botha be removed from the Pistorius case.
