Seven Cameroonian athletes have fled from their accommodation at the Commonwealth Games in Australia, team officials said on Wednesday.
The number of the missing athletes may even go higher as organisers of the game in Gold Coast verify the whereabouts of two squash players from Sierra Leone.
The developments came a day after Cameroon revealed eight of its 42-strong Games team are missing, including two boxers who failed to appear for their bouts.
"The focus now is to support teams in trying to track down the athletes who are missing".
A statement said testimony from an Australia Sports Anti-Doping Authority (ASADA) investigator was "credible", and cast doubt on comments from the two athletes.
Commonwealth Games Federation CEO David Grevemberg confirmed in a statement that Australian authorities are now searching for "one Rwandan and two Ugandan accredited delegates not present in the village".
"The team was here in Warwick training, but the reality is we are three hours away from the Gold Coast, it is quite a trip", Cr Dobie told news.com.au.
On Wednesday, Cameroon's team attache Simon Molombe told CNN Sport he did not expect the missing athletes to return: "I don't think they will be back", he said.
"But out here, only six of them effectively took part in their respective competitions, while two left without competing".
Games officials say the athletes have not yet officially breached their visas, which do not expire until May 15.
The Commonwealth Games Federation said: "The athletes have the right to travel freely on their visas", but admitted that they are monitoring the situation.
It is not the first time athletes have disappeared during major sporting events.
During the London 2012 Olympics, 21 athletes and delegates either vanished or asked for asylum in the UK.
Ian Natherson from Ready Migration said a majority of the calls he received were from African athletes including those from Ghana, Nigeria and Mauritius.
"We would appreciate them sticking within the law - enjoying themselves but sticking within the law", Mr Beattie said.
"Our message is the 0.5% of people who might think they can overstay a visa, or not act within the considerations of that visa, is that Australia has very tough laws and they need to abide by those laws", Mr Dutton said.
