Suzanne Harrison, 38, admitted four counts of sexual assault
against the girl - who cannot be named - between December 2005 and
July 2006, Ipswich Crown Court heard.
The news is the latest incident to see a female teacher formally
investigated over her relationship with a female pupil.
Prosecutor Godfried Duah told the court that Harrison pursued
the victim at her fifteenth birthday party. Once ingratiated, she
then spent considerable time with the girl and her family before
making sexual advances towards her.
This continued for several months and was said to have had
"considerable impact" on the victim.
Duah added that even when the girl had moved on to university, she
was subjected to "emotional abuse" by her former teacher.
Now, the judge has ruled that Harrison should be detained in a
psychiatric hospital.
Judge Peter Thompson said he had made the ruling after a "very
thorough" assessment of her condition.
"This does not mean the court takes a less serious view of the
offending - the victim has suffered very significantly, " he told
the court.
