US police has released bodycam video footage which shows when they first responded to the gunman who shot Donald Trump in Pennsylvania last month.
The former US president was injured in the assassination attempt at a campaign rally in Butler.
The suspect, 20-year-old Thomas Matthew Crooks, was shot and killed by the Secret Service.
In the video which was released by Butler County, local law enforcement officers are seen helping each other onto the roof used by Crooks, climbing a ladder and eventually reaching Crooks body after he was shot.
According to the video's timecode, an officer can be heard shouting "he was on top of this building, the left one" at 6.15pm.
Last month Kevin Rojek, the special agent in charge of the FBI's Pittsburgh field office, told reporters at a briefing that Crooks was seen carrying a backpack around 5.56pm, less than 20 minutes before the shooting took place.
At 6.08pm he was caught on a police dashboard camera walking on the roof from where he ultimately fired the shots.
Crooks' body can be seen a few steps away from the officers on the roof.
Crooks was able to crawl across the roof overlooking Mr Trump's rally and fire eight bullets from a semi-automatic rifle before he was fatally shot by a Secret Service sniper on another building, according to law enforcement reports.
The gunman killed one man in the crowd and critically wounded two others. Mr Trump was wounded in the right ear.
