Venezuelan police have arrested two brothers in connection with the killing of a top government prosecutor.
Officials said Friday, Rolando and Otoniel Guevara were arrested west of the capital city of Caracas.
Their arrest comes the same week that police shot and killed two other suspects in the prosecutor's murder.
Prosecutor Danilo Anderson died when explosions ripped through his car as he drove through the Venezuelan capital.
Officials have said the attack may have been politically-motivated.
Mr. Anderson had been overseeing a case against hundreds of opposition politicians, businessmen and former military officers involved in a 2002 coup that briefly ousted President Hugo Chavez.
Two former Caracas police chiefs who were being investigated by Mr. Anderson sought asylum Friday at El Salvador's embassy in Caracas.
