JAKARTA - Acting Secret Service director Ronald Rowe of the United States (US) police in Pennsylvania warned there was a gunman on the roof before the attempted murder of Donald Trump. But the message did not reach the Secret Service agent on time.

Local authorities and Secret Service agents use different communication channels. Therefore, the warning was not delivered before a 20-year-old striker opened fire on a Republican presidential candidate.

"In the last 30 seconds - the focus of what happened before the attacker opened fire - was clear there was a possible radio transmission in the local radio network that we didn't have," Rowe said.

Rowe said the FBI, the agency leading the criminal investigation into the shooting, was trying to determine exactly what was communicated.

But Rowe said investigators believed someone delivered it via radio they had seen the person carrying a gun.

A local police officer faced a shooter on the roof of an industrial building where he finally opened fire.

But the officer, who was picked up by a colleague, fell to the ground about 30 seconds before the attacker started shooting, law enforcement officials previously said.

At the time of gunfire, Secret Service learned local police were handling issues around the scene, but did not know about the weapon.

In his testimony before Congress on Tuesday, Rowe blamed local law enforcement failures and also said he was "blame" for the security flaws that occurred on the day of the shooting.

Rowe also noted that Secret Service was not present at the command post established by local law enforcement in Butler, Pennsylvania for the ex-presidential outdoor campaign.

The first shooting of a US president or presidential candidate from a major party in more than four decades was a flagrant security breach that led to the resignation of Secret Service Director Kimberly Cheatle under pressure from congress bipartisans.

Officials said Thomas Crooks (20) fired a shot that injured Trump's right ear, killed a public meeting participant and injured two others with an AR-15 rifle, before law enforcement snipers shot the perpetrator dead.
