Police are appealing for witnesses following an assault in Kettering.
The incident happened in the early hours of Sunday, June 23, between 1.50am and 2am.
A 20-year-old woman was waiting at a taxi rank on Horsemarket when another woman attempted to jump the queue. An argument broke out between the women and a group of men who were also waiting in the queue.

She was wearing a dark-coloured vest and had a distinctive star tattoo that went from her neck down to her left breast.
