Samantha Taylor, an ex-girlfriend of Pistorius, said that on one or two occasions while she had been at his home, he had believed there could have been a burglar in the house.

Oscar Pistorius had previously believed an intruder was in his house, the High Court in Pretoria heard on Friday.

Samantha Taylor, an ex-girlfriend of Pistorius, said that on one or two occasions while she had been at his home, he had believed there could have been a burglar in the house.

She recalled one night when Pistorius heard something hit against the bathroom window.

"One occasion... he woke me up and asked if I had heard it. I told him it was probably the storm," said Taylor.

He said Pistorius took his gun, and he and a friend who was living with him at the time went to investigate. The two men found nothing.

Pistorius is on trial for the murder of his girlfriend, Reeva Steenkamp, whom he shot dead through a locked bathroom door in his Pretoria home.

He says he mistook her for an intruder.

The State, however, argues that it was premeditated murder.

Taylor completed delivering her evidence on Friday afternoon before the court adjourned for lunch.
