A former ballet tutor at a dance school in west London has been found guilty of thirteen counts of sexual assault.

Yat-Sen Chang, 49 (16.10.1971) of Theatre Kiel, Germany, was found guilty of the offences on Tuesday, 11 May after a two-week trial at Isleworth Crown Court.

This case concerns allegations of sexual assault made by four victims, victim [A], victim [B], victim [C] and victim [D].

At the time of the offences, Chang was a ballet tutor at a dance school in west London.

In 2016, police were contacted by victim [A] and victim [B] who alleged seven sexual offences against Chang over a two-year period.

Following this, victim [C] and victim [D] came forward and alleged seven sexual offences against Chang over a three-year period.

This referred to instances of sexual assault that occurred during private ballet tuition lessons held by Chang with each of the victims.

Following these allegations, an investigation was launched by officers from the West Area Child Abuse Unit.

Chang was arrested on 14 April 2016 on suspicion of sexual assault and further interviewed on 27 August 2020. He denied all allegations against him.

Chang was charged twice, first on 12 December 2019 and again on 10 November 2020, for a total of 14 counts of sexual assault on four females. These charges related to incidents that occurred between 1 December 2009 and 10 April 2016 at a dance school in west London, his private residence and a London ballet school.

After a trial that lasted just over two weeks, Chang was found unanimously guilty of twelve counts of sexual assault on a female, and guilty of one count of sexual assault by penetration of a female. He was acquitted of one count.

He is due to be sentenced at Isleworth Crown Court on Tuesday, 18 June.

Detective Constable Helen Larson, of the West Area Child Abuse Unit, said: “Chang is a dangerous and predatory individual who targeted these young victims. He abused his position of trust and power to prey on them when they were most vulnerable.

“The victims showed extreme bravery and courage in reporting the incident and helping us to bring Chang to justice. I am sure that this will prevent further offences from taking place.

“It remains a top priority for the Met to tackle and prevent instances of sexual assault, putting offenders behind bars and bringing justice to the victims. I encourage anyone who has been a victim or witnessed a sexual assault to contact police. We have specially trained officers who will give advice and take all allegations seriously. You will be supported.”
