A female teacher ripped open a male colleague's shirt and grabbed his testicles, a misconduct hearing was told.

Helen Evans, 44, left her colleague feeling 'intimidated and extremely upset' when she allegedly groped him at a parent-teacher evening.

Her colleague gave up teaching shortly after the alleged 'sexually motivated' attack - and said Miss Evans' behaviour was the main reason.

Primary school teacher Miss Evans did not deny the incident happened and was reported to police - but the Crown Prosecution Service decided not to take the case any further.

She is also accused of bringing in a snake without permission - terrifying a phobic colleague - and allegedly called senior staff at the school 'dumb and dumber'.

A Fitness to Practice hearing was told the alleged incident took place at Llanishen Fach School, Cardiff, in May 2013.

Headteacher Sarah Coombes said the male teacher alleged the assault happened at a parent-teacher event.

She said the colleague felt 'intimidated and extremely upset' and his self esteem was lowered in the 'sexually motivated' incident.

Miss Evans is also accused of bringing a snake into the school in 2015 without a risk assessment.

Ms Coombes said: 'Colleague C has an extreme phobia of snakes and was not made aware of the visit.'

Miss Evans, who worked at the school for 22 years, also allegedly called senior staff 'dumb and dumber' as they entered a room.

The hearing was told she failed to mark books correctly - using phrases like 'wicked dude' and 'love it babes' - before being dismissed in April 2015.

Presenting officer Hannah Eales said the allegations related to 'bullying behaviour and sexually motivated actions'.

Miss Evans is accused of failing to follow management instructions, behaving unacceptably towards colleagues and making inappropriate comments.

She is also accused of providing inaccurate information and behaving dishonestly with regards to pupils work.

The Education Workforce Council hearing, which Miss Evans is not attending, is continuing.
