Police investigating a seemingly unprovoked assault on two men in the Yeading area have released this image of a man they would like to interview.
They were called on Sunday (11 July) at 11.19pm to a stabbing near the junction of Willow Tree Lane and Reynolds Road.
Two men, aged 21, were taken to hospital with stab injuries and remain there in a stable condition.
Reports suggest they were walking along Willow Tree Lane with a third person when they were confronted by a man not known to them.
They became involved in an argument and the man lashed out before leaving in the direction of Yeading Lane.
Police have reviewed a large amount of CCTV and are releasing an image of this man, who could have important information about the incident.
