Australian Border Force were searching for weightlifters Olivier Matam Matam, Arcangeline Fouodji and Petit David Minkoumba and boxers Ndzie Tchoyi and Simplice Fotsala after they apparently fled.
Eight Cameroonian athletes have gone missing from their accommodation at the Commonwealth Games in Australia. Officials said they are monitoring reports of the absences from the federations.
"In the meantime, the other two weightlifters of the delegation, along with the basketball players and officials, have already left Australia and are presently airborne for Cameroon", he said.
"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.
Yombo's disappearance means O'Reilly advances to the semi-final and will at least receive a bronze medal.
Cameroon chef de mission Victor Agbor Nso said the eight athletes who had left the village did so at three different stages.
Cr Dobie said there was no indication they were unhappy and "they were great ambassadors for their country, there was no indication at any time that there was an issue with individuals".
Mr Molombe said the incident was very worrying.
Eagles soar on Federation Internationale de Football Association ranking
Belgium's move up the rankings means UEFA Euro 2016 champions Portugal have slipped down to fourth and Argentina now sit fifth. Tunisia (14), Senegal (28), Congo DR (38), Morocco (42) and Egypt (46) are all above Nigeria (47) in the African Ranking.
"It's very worrying, it's not good for the image of the country".
It is not the first time Cameroonian athletes have gone missing while competing in the West.
"If there is a breach then [Home Affairs Minister] Peter Dutton and the department will deal with it", he said.
"But these athletes are guests here in Australia, they are still within their visas and they have the right to travel freely", Grevemberg said.
Rwandan officials have also confirmed one of their coach failed to return to the athletes' village after the para-powerlifting competition at Carrara on Tuesday and police are unaware of his movements since.
"We share their concern regarding obviously the safety, welfare, whereabouts of these athletes".
Adding to the confusion of the situation, a Cameroon official told reporters at the Games boxing venue none of his athletes were missing.
The Australian government has warned athletes against overstaying their visas.
