A teenager is due to appear before magistrates this morning charged with a serious sexual assault.
The 19-year-old man, of no fixed abode, is due to appear at Northampton Magistrates Court following a report of an attack almost a fortnight ago.
Officers were called to an address in St James on February 1, between 7am and 7.30am, where an alleged serious sexual assault was reported.
A 19-year-old man was arrested and has since been remanded into custody.
Anyone who may have further information is asked to contact Detective Inspector Helen Knight on 101, in the strictest confidence.
