Sydney teacher Helga Lam accused of sexually abusing three teens

A female teacher will face a criminal trial after being charged with sexually abusing three teenage boys at a Sydney high school.

A Sydney teacher will face a trial over allegations she sexually abused three schoolboys more than 40 years ago.

Helga Lam, 67, was arrested in September last year following a four-month investigation by police into the alleged sexual assault of three boys at Maroubra Bay High School between 1977 and 1980.

Police established Strike Force Sportsground to conduct the “extensive” investigation.

Detectives allege three boys - aged 13, 14 and 15 - were assaulted by Ms Lam while they attended the school.

Ms Lam was arrested at her St Ives home and was taken to Hornsby Police Station where she was charged with 14 counts of indecent assault.

Following further investigation Ms Lam, who was employed as a teacher in Sydney at the time of her arrest, was hit with three further charges.

The 67-year-old last week entered pleas of not guilty to all 17 charges of indecent assault on a male.

She has now been committed to stand trial in the NSW District Court.

Ms Lam was granted strict conditional bail and will reappear in court for arraignment in August.

Maroubra Bay High School closed in 1990, ten years after Ms Lam’s alleged offences ceased, and was used to film five seasons of soap opera Heartbreak High.

The site was later developed for residential units.

At the time of her arrest, Ms Lam was working at Killara High School on the city’s upper north shore.
