Chemical attack part-blinds girl, 13, in Islington

A grandfather has spoken of his fury after his teenage granddaughter had ammonia thrown in her face in an apparently unprovoked attack.

The 13-year-old was walking in Islington, north London, with two friends at 2210 BST on Saturday when they were attacked.

The girl has been left partially blind in one eye. Doctors have said it could be permanent.

A boy, 14, has been arrested and bailed to return to police in late June.

The girl has asked not to be identified because she is afraid of another attack.

Her grandfather told the BBC: "A crowd of boys came riding past her and one of them sprayed her with ammonia.
