Stockholm  - A 31-year-old German woman extradited to Sweden on suspicion of beating two children to death remained in police custody Thursday.

The woman's lawyer Per-Ingvar Ekblad met his client Wednesday, the day after she arrived in Sweden, and told reporters she maintained she was innocent of allegations she killed the two children, aged one and three, in March.

The German student is being held in Vasteras, about 100 kilometres west of Stockholm, and is restricted from reading newspapers and listening to the radio pending a remand custody hearing due Saturday.

Police said they aimed to interview the woman Friday.

Swedish authorities have cooperated with prosecutors in the German city of Celle over the case.

The head of the investigation, Bo Forsman, said the police were still waiting for results from DNA tests, including of a hammer believed to have been used in the attack.

The woman student denies allegations, widely aired in the media, that after she was jilted by a Swedish boyfriend, she had attacked his new girlfriend and the Swedish woman's children from previous relationships.

The Swedish woman, 23, survived the attack in the town of Arboga in March but reportedly cannot remember what happened.

The woman, who recently left hospital, said the hearing in her right ear was impaired and she was also injured in one eye, the local newspaper VLT said. (dpa)
