Eleven crimes were reported in Oscar Pistorius's townhouse complex in three years, the High Court in Pretoria heard on Tuesday.

Two of these were the killing of Pistorius's girlfriend Reeva Steenkamp, allegedly by Pistorius in his home in the Silver Woods estate on February 14, 2013, and the theft of one of his watches hours afterwards, Warrant Officer Hendrick Maritz said to questioning by prosecutor Gerrie Nel.

The third was a house robbery on the estate on October 24, 2011.

"And there were no other house robberies or burglaries?" Nel asked.

"None we could pick up on our system," Maritz replied.

The statistics Maritz was being questioned on covered the period January 2011 to April 2013. The estate is in the Silver Lakes area of Pretoria.

Pistorius is on trial for the murder of Steenkamp. He claims he shot her through the locked door of his toilet thinking she was an intruder.

Shortly after the shooting, while the police forensics team was on the scene, one of Pistorius's expensive watches was stolen from his bedroom.

Maritz is attached to the crime information office of the Boschkop police station and tasked with compiling daily reports on which areas crimes are committed in.

Nel asked Maritz if Pistorius had ever appeared on the police's case administration system as either a complainant or an accused before February 14, 2013.

He replied no.

Barry Roux, for Pistorius, then began his cross-examination.

Maritz said the statistics he used were only crimes reported to police.

Roux said that on the evening of Steenkamp's death the police who attended to the scene at Pistorius's house had just come from a house robbery at another estate.

He said the court had also heard previous testimony that living in a security estate was not a guarantee of safety.

When Roux had concluded, Nel had Maritz explain how crimes reported were not recorded on the police computer systems.

This could occur through typing errors on the name or identity number of the complainant, Maritz said.
