A suspect held after a crossbow bolt was fired on to the field during a county cricket match has been released without charge.
The 35-year-old man was arrested on suspicion of attempted grievous bodily harm following the disturbing incident during the game at The Oval last month.
Surrey and Middlesex players were rushed from the pitch when the umpire saw the bolt hurtle into the ground.
Armed police evacuated 1,000 spectators from the ground amid initial fears of a terror attack, and the match was abandoned as a draw.
There were no reported injuries, but police believe the bolt may have been fired from a nearby roof terrace.
The suspect was released on bail, pending further inquiries.
But a Met Police spokesman said: "A 35-year-old man has been released without charge and will face no further action."
He confirmed that the investigation is ongoing.
