A SPURNED schoolgirl left a love rival with horrific injuries after pouring sulphuric acid into her viola case.

The 17-year-old pupil victim was hit by the acid solution when she took the case down from a shelf.

Edinburgh Sheriff Court heard the girl was left screaming in pain and suffered severe burns to her legs at a school in East Lothian last year.

The court heard the attacker, also aged 17, had researched acid attacks and how long acid attackers might receive in prison.

Prosecutor Aiden Higgins said the girls’ “friendship came to an end after the break-up of the accused’s year-long relationship with a boy. Matters became worse when the victim began a relationship with the former boyfriend”.

The girl admitted the attack and will be sentenced next month.
