Police were stationed in building Trump gunman shot from

Police were stationed inside the building from which gunman Thomas Matthew Crooks fired shots at Donald Trump, the director of the US Secret Service Kimberly Cheatle says.

Ms Cheatle told ABC News that local police were inside the building while Crooks was on the roof, and that local police - not the Secret Service - had been “responsible" for securing the building and its outer perimeter.

Questions have swirled about how police officers and agents tasked with securing Trump's Pennsylvania rally allowed Crooks to get as close as he did.

He was able to access the roof of a building near the outdoor event at Butler County fairgrounds, Pennsylvania, from where he shot at Trump 130m (430ft) away.

The local police deployment inside the building comprised three snipers, who are alleged to have seen Crooks trying to get on the roof, according to sources quoted by CBS News, the BBC's US partner.

One audience member was killed and two others critically injured in the shooting. Trump was wounded in the ear.

Secret Service spokesman Anthony Guglielmi said that his agency was responsible for securing inside the perimeter of the fairgrounds, while local police secured the area outside, which included the private building used by the gunman.
