Pretoria - A foreign journalist filing his report after the first day of Oscar Pistorius's murder trial made his sister Aimee frown in the High Court in Pretoria.

The reporter, speaking the Queen's English into his cellphone moments after Judge Thokozile Masipa adjourned proceedings for the day, said the paralympic athlete “looked like an unconcerned spectator” and “appeared to be on some kind of medication”.

Aimee and Carl Pistorius were standing in the front row of the public gallery in court GD, with the portly journalist four benches behind them.

They were looking in his direction and frowned and turned away when they heard him.

Pistorius's trial for the murder of his girlfriend, model and law graduate Reeva Steenkamp, continues on Tuesday at 9.30am.
