RIO DE JANEIRO (AP) The Latest on the 2016 Summer Olympics being held in Rio de Janeiro (all times local):

A Brazilian police officer has died after being shot in the head when he and two others working security at the Rio Olympics got lost near a slum and encountered gunfire.

Justice Minister Alexandre de Moraes announced Helio Vieira's death early Friday on his official Facebook page.

The officers from Brazil's national security force were using a GPS device to navigate unfamiliar streets Wednesday afternoon when they took a wrong turn off a highway leading to Rio's international airport. Their truck was sprayed with bullets, shattering the windows.

Viera died late Thursday and the other officers suffered minor injuries.

More than 85,000 security forces have been deployed in Rio for the Olympics, which is double the number of London in 2012.

Several swimmers have been listed with the wrong qualifying times coming into the Rio Olympics – raising even more questions about the way world swimming body FINA is governing the sport.

FINA did correct some mistakes, including that of a Kuwaiti swimmer competing under the IOC flag.

The Guardian newspaper in Britain reported that 17 swimmers from 16 countries still had qualifying times that didn't match their actual results from last year's world championships. All were admitted to the games under the ''universality rule,'' which aims to spread the sport to developing countries that would not otherwise have qualified.

In a statement Friday, FINA said the Olympic competition in Rio was not affected by the wrong times.

FINA did change the qualifying times for several dozen swimmers, as well as some relay times for major teams such as Italy and Hungary. The times determine heats and lane assignments during preliminary heats.

Fiji has its first-ever Olympic medal – and it's gold to boot. Now that's a reason to party.

The Pacific Island nation erupted with joy Friday after its rugby sevens team crushed Britain 43-7 in final in Rio de Janeiro.

In the capital of Suva, fans packed the 15,000-seat National Stadium to watch the Olympic final on a big screen – held Thursday night in Rio but at 10 a.m. Friday back home. Tense at first as they saw their nation on the brink of an historic achievement, fans relaxed and then rejoiced as Fiji ran away with the victory.

Prime Minister Frank Bainimarama, in Rio for the games, told reporters ''rugby has always lifted the spirit and always brought us together. Right now, whatever political party, there's no difference. Everyone is coming together to celebrate.''

He declared a public holiday for Aug. 22, the day after the team returns home.

Chinese officials say a female Chinese swimmer has tested positive for a banned substance at the Rio Olympics – the first competitor in the sport to fail a test at the games.

The Chinese Swimming Association says 18-year-old Chen Xinyi has tested positive for the diuretic hydrochlorothiazide after she finished fourth in the women's 100-meter butterfly Sunday, missing a bronze medal by nine-hundredths of a second. Xinhua, China's official state news agency, reported the story Friday.

Chen was also scheduled to compete Friday in the 50 meter freestyle.

Chen has applied to the International Olympic Committee to have her B sample tested and to get a hearing on the matter, Xinhua said, citing the swimming association, which promised in a statement to ''take this matter seriously.''
