LOS ANGELES - US Republican presidential candidate Donald Trump was rushed off stage by security Saturday night during a disturbance at a campaign rally in Reno, Nevada, but returned to the stage after a few minutes and finished his speech.

Some kind of disturbance occurred in the front of the room where Trump was giving speech. As Trump put up a hand above his eyes to peer out into the crowd, two security officials rushed to his side and escorted him off stage.

Audience in the room suddenly scattered as law enforcement agents made their way into the crowd to apprehend an unidentified man.

A Secret Service spokesperson said in a statement that there was an "unidentified individual" in the crowd shouting "gun", though no weapon was found after a "thorough search."

The Secret Service did not immediately provide further details, saying an investigation was ongoing.

A man in a blue hoodie was tackled before being escorted out by law enforcement and being held in a bathroom inside the venue. The man was reportedly released later and no charge was filed against him.

Trump returned to the stage unharmed about five minutes later and continued to finish his speech.
