Sydney teacher accused of abusing girls

A former primary school teacher who allegedly indecently assaulted three of his young female students has been arrested in Sydney's west.

Two of the students were aged 11, while another was nine years old, police say, adding that detectives began investigating the assaults following a report from a student in May.

The 49-year-old male teacher was charged with nine offences including seven counts of aggravated indecent assault on Wednesday and was refused bail to appear at Penrith Local Court on August 26.
