Accused teacher Christopher Hird known as 'Mr Perv'
A science teacher accused of touching girls in his class was known by his pupils as "Mr Perv", according to one of his alleged victims.
Christopher Hird, 47, of Highfields, South Cave, denies sexual misconduct with three girls at the secondary school in East Yorkshire.
Hull Crown Court was told the alleged touching was "brief and subtle" but it "upset and stayed with the girls".
The offences are said to have happened between 2000 and 2012.
Simon Waley, for the prosecution, said the first girl who came forward alleged Mr Hird touched her twice during lessons in 2011 and 2012.
She was 15 when she said it first happened and claimed he wiped ink from her face, stroking her in a way she found "quite disturbing".
'Staring at girls'
The court was told in the second incident Mr Hird came up behind her in the classroom when she asked a question and pressed himself against her.
He is alleged to have also placed his hand on the chair between the girl's legs.
When the incident was reported, the school told police about another allegation made in 2009.
Mr Waley said this girl, who was 16 at the time, told police Mr Hird was known among pupils for staring at girls' chests and was nicknamed "Mr Perv".
She accused him of brushing his hand against the side of her breast in class.
The third girl came forward about an alleged incident in 2000 after the teacher was charged and a story about the case featured in a newspaper.
The court was told she was aged 11 and in her first week at school when she claimed he touched her inappropriately as he removed a piece of paper she had been sitting on.
The trial continues.
