The man was part of a group of students confronted by a larger group of people at the corner of South Parks Road and St Cross Road in Oxford on Saturday night, police said.

The victim was hit with the bottle before the larger group ran off at about 10.45pm, spokesman Rebecca Webber said.

The incident is being treated as GBH but no-one has been arrested.
