A man has been arrested for the murder of Roodepoort schoolgirl Louise de Waal, according to news reports

According to Beeld newspaper, the police had been investigating a man in the Roodepoort area after finding De Waal’s school bag in a car that matched the description her friend gave to police.

On Wednesday morning, a bakkie pulled up alongside two girls walking on the corner of Rina and Herman streets in White Ridge around 7am.

“A man got out and ordered the teenager into the vehicle. When the girl refused, he pointed a firearm at her until she complied,” police said.

The other girl, Natasha Gordon, ran away and the bakkie sped off with her friend.

Her burnt body was later found on a farm in Magaliesberg.

Louise's mother, Shireen de Waal, speculated to Beeld about her daughter’s modelling pictures, saying she wondered if she had posted them on social networking site Facebook.

“Louise was never violent, she never felt hatred for anyone, she’s my angel. I truly believe she’s a spirited child who God has touched,” the grieving mom told The Star.
