A female primary school teacher sexually assaulted her male colleague after ripping open his shirt at a parent's evening, a tribunal was told.

Helen Evans, 44, left her victim "intimidated and extremely upset" when she allegedly ripped open his clothing before grabbing his testicles.

Evans was accused of carrying out the sexual assault during a parent-teacher event at Llanishen Fach Primary School, Cardiff in May 2013.

Evans, who had taught at the school for 22 years, did not deny the incident happened and was subsequently reported to police.

However the Crown Prosecution Service decided not to take the case any further, it was heard.

The male staff member quit his teaching post after the incident and blames Evans’ behaviour for his departure, a fitness to practice hearing was told.

Llanishen Fach Primary School’s headteacher Sarah Coombes said the male teacher's self esteem was lowered as a result of the "sexually motivated" encounter.

She said another colleague had described Evans as "rude, abrupt and confrontational."

The 44-year-old was sacked in April 2015 over seven allegations alleged to have amounted to gross misconduct.

She was accused of bringing a snake into the school in 2015 without a risk assessment and marking pupils' books with inappropriate comments.
