A device found with the man who tried to assassinate Donald Trump was a remote fireworks detonator, according to US law enforcement sources.
The grey 12-button handset was found next to Thomas Crooks’ phone after Secret Service shot him dead when he opened fire on the former president.
It’s believed it could be linked to what the FBI called a “rudimentary” explosive device found in his car.
Authorities think it was probably intended as a distraction or to injure law enforcement rather than to cause a significant explosion.
Crooks, 20, grazed Trump‘s ear with one of his shots as the ex-president addressed supporters in a field in Butler, Pennsylvania, on Saturday.
Investigators are digging into his past for a motive for an attempted assassination that experts say was a huge lapse of security.
The gunman was able to take a prime position on a roof about 130m away and warnings by people who spotted him appear to have gone unheeded or not treated urgently enough.
Crooks had driven to the venue, parking at a petrol station about a third of a mile away, after buying 50 rounds of ammo from a local gun shop.
His motivation remains elusive despite searches of his devices and home, and interviews with more than 100 people.
No sign of strong political views have been uncovered and those who knew him described a loner who was rejected from the school rifle team for being a poor shot.
He did, however, manage to become a member of a local shooting club through his family – and the day before his attack reportedly went there to practise.
“He was an odd kid, but nothing about him seemed dangerous,” said former classmate Liam Campbell.
“Just a normal person who seemed like he didn’t like talking to people.”

Audience member Corey Comperatore, 50, was killed as he shielded his family and two others were seriously wounded.
Mr Trump said he survived due to divine intervention after moving his head slightly as the bullets flew in – with one remarkable photo appearing to capture one mid-flight.
The attack has sparked fresh concern over the feverish tone that can often consume US politics, with President Biden calling for unity in a live TV address.
All eyes are now on Trump’s address to the Republican party conference on Thursday, for a speech he said he’s re-written in light of the attempt on his life.
