A teenager has pleaded not guilty to sexual assault.

The 13-year-old, from Epping, appeared at Chelmsford Youth Court on Friday over the attack on a 53-year-old woman.

The boy is also accused of possessing a Sumarai sword in High Street, Epping, and having a kitchen knife on the premises of Epping St. Johns School on June 11.

He allegedly groped the woman at her Epping home on June 26. 

The boy pleaded not guilty to all three offences and now faces a two day-trial, beginning on January 30 next year.

He has been remanded on conditional bail.
