An investigation is underway after two men were assaulted in Shepherds Bush.
Police were called at 03:53hrs on 13 September by the London Ambulance Service (LAS) after two men were found suffering injuries in Uxbridge Road, near to Shepherds Bush Green, W12.
The two men - victim 1 aged 48 and victim 2 aged 19 - were treated at the scene for head injuries and taken by LAS to a central London hospital for treatment.
Neither man's condition is life threatening.
At this early stage it appears both men were assaulted by a bottle.
