A 14-year-old girl has been arrested in connection with a stabbing in Summertown, which left a teenage boy with serious injuries.

The girl was arrested on Wednesday on suspicion of conspiracy to commit grievous bodily harm in connection with the incident last month.

A 17-year-old boy suffered serious neck and arm injuries during a fight at the junction of Middle Way and Rogers Street shortly before 10pm on February 15.

He was discharged from hospital several days later.

Police said the investigation is ongoing and appealed for anyone with information to come forward.

The 14-year-old has been released under investigation.
