PRETORIA - Defence advocate Barry Roux on Wednesday told the North Gauteng High Court that Oscar Pistorius's toilet door was tampered with.

A battered door, a forensic expert and a cricket bat signed by Herschelle Gibbs all featured on day eight of the athlete's murder trial.

The 27-year-old is accused of murdering his 29-year-old girlfriend Reeva Steenkamp on Valentine's Day last year.

The Olympic and Paralympic star also faces gun-related charges for two separate incidents in the Vaal and at a crowded Johannesburg restaurant.

Forensic expert Gerhard Vermeulen on Wednesday told the Pretoria court about how the cricket bat was used to break through a toilet door shortly after the deadly shooting.

The 'Blade Runner' shot and killed the model through the toilet door.

Vermuelen demonstrated how the signed cricket bat was used to bash down the structure.

The bullet-riddled door was set up close to the witness box to recreate the crime scene.

Colonel Gerhard Vermeulen demonstrates how Oscar Pistorius might have used a cricket bat to break down the door through which he shot and killed Reeva Steenkamp in February 2013.

Colonel Gerhard Vermeulen reveals details of what might have taken place during the time Reeva Steenkamp was shot and killed.

The forensic expert got down on his knees and swung the bat to demonstrate how Pistorius would have smashed through the door.

The state tried to show that Pistorius was in all likelihood on his stumps when he tried to break it down.

Prosecutor Gerrie Nel clarified that the state believed Pistorius was wearing his prostheses when he fired the shots.

During cross-examination, Roux said there were additional marks on the door that weren't there before.

He raised questions about how the evidence was preserved while in police custody.

Roux then claimed the door had been tampered with.

The advocate and Vermuelen discussed at length the condition of the door when the shots were fired.

Roux suggested when the door was taken apart as part of the investigation, officers stepped on the panel with the bullet holes - an integral part of the evidence.

Vermeulen could not explain the prints or the marks.

Roux says he will produce evidence showing that his client first kicked the door, before collecting the bat.

This is not the first time police have been accused of inefficiency in dealing with evidence in the Pistorius matter.

Former lead investigating officer Hilton Botha was accused of not wearing covers on his shoes when attending to the crime scene.

In February 2013, National Police Commissioner Riah Phiyega announced a new investigating officer was assigned to the high-profile murder case after Eyewitness News revealed Botha was facing seven charges of attempted murder.

In March last year, police revealed Botha resigned from the force.

The proceedings have been adjourned for the day.
