South African Paralympic icon and murder suspect Oscar Pistorius today said he was thankful for prayers offered to his family and that of his slain girlfriend, a day after he was freed on bail.

"Thank-you to every person that has prayed for both families, Osca" read a tweet posted by his brother Carl, in the track star's first public reaction, outside of his court appearances, since his arrest for the Valentine's Day killing of Reeva Steenkamp.

The Olympic "Blade Runner" was spending his first day out on bail with his family pending trial for the killing of his lover.

Pistorius was freed on a record one million rand ($112,770) bail yesterday after eight days in custody and an emotionally charged four-day bail hearing.

"I would like Oscar to just compose himself and to have a normal day," his uncle Arnold Pistorius told the local Eyewitness News.

He will return to court later this year when a date will be set for trial for having shot dead his model girlfriend and law graduate Reeva Steenkamp on Valentine's Day.

When contacted by AFP, his father Henke Pistorius declined to say how his son had slept at his uncle's house in Pretoria.

But a source close to the family told AFP late last night that "the family just want time together. They haven't thought about anything except being together."

Pistorius claims he repeatedly shot at and killed his lover by mistake thinking she was a burglar.

Steenkamp's grieving parents, however, did not appear convinced.

"It doesn't matter how rich he is and how good his legal team is. He needs to live with himself if he lets his legal team lie for him," her father Barry told the Afrikaans-language daily Beeld.
