An investigation has been opened after a bullet entered the media tent at the Olympic equestrian centre on Saturday.
Nobody was injured in the incident, which saw a military bullet reportedly land at the feet of photographers. A military base is adjacent to the equestrian centre in Deodoro.
Phil Wilkinson, Rio 2016's international media manager, confirmed to Omnisport that the episode, which left a small hole in the roof of the tent, was being investigated.
News of the stray bullet followed a controlled explosion of a suspicious package near the finish line of the men's cycling road race, which was carried out as a precaution.
