LONDON  —  Prince Harry (search) arrived home from Argentina Friday amid media reports that shots were fired at the ranch where he had been staying.

Clarence House, the office of Harry's father, Prince Charles (search), said Harry had been scheduled to return Friday and refused to comment on reports in the Argentine media about an alleged incident at the polo farm complex in Salvador Maria where he had been staying.

Argentine news reports said that security guards at the gate of the complex heard shots in the early hours Wednesday and had responded by firing into the air.

News Web site Clarin.com said police in Lobos believed the shots were from poachers and that Harry, 20, who had been working at the farm for most of November, was never in danger.

Clarence House said Harry stayed at the British High Commission in Buenos Aires Thursday night.

He arrived at Heathrow Airport Friday morning aboard a scheduled commercial airlines flight from Buenos Aires.

Looking relaxed in a pale blue open-necked shirt and blue denim jeans, Harry made no comment to reporters as he left a VIP lounge at the airport and departed by car.

The prince had always planned to return to Britain Friday, a Clarence House spokesman said on customary condition of anonymity.

Harry is the third in line to the British throne, after his father and older brother, Prince William (search), 22.
