The 24-year-old, who actually finished second behind Australian Sally Pearson after she was disqualified for a false start, tested positive for the stimulant methylhexaneamine and has requested that her B-sample be analysed.

The Nigerian, who was set to compete in the 200m, as well as the 4x100m Nigerian relay team, has now been provisionally suspended and faces a hearing later today.

Oludamola had ironically told reporters after the race: "I want to put Nigerian sprinting back on the map."

It appears she has now done so, but for all the wrong reasons as a downbeat Commonwealth Games Federation President Mike Fennell announced the grim news at a press conference this morning.

Fennell said: "We have conducted over 950 drugs tests and I have to report that we have had a positive result.

"That result was in relation to the winner of the 100m final, the Nigerian Osayemi Oludamola.

"She has been notified in accordance with the anti-doping standard that applies to the Games.

"She has requested the testing of the B-sample.

"The B-sample will be tested by the laboratory and a hearing will be held later today.”

The news is a devastating blow to one of the blue-ribbon events at the Games, with the track and field athletics competition already devoid of many of its top stars, including Jamaican sprint sensation Usain Bolt and English heptathlon star Jessica Ennis.

Fennell admitted he has no idea "the sort of damage" the positive test will do to the Commonwealth brand and said he was devastated to learn of the news.

"Any positive test is to be regretted because we are all striving for a clean Games and clean competition," he said.

"But I want to assure everyone that we are being vigilant with our testing."

Secretary General of the Organising Committee Lalit Bhanot said the announcement is a warning for athletes.

"We want dope-free Games," said Bhanot.

"That’s why 1,500 tests are being conducted.

"If someone is caught, action will be taken as per the rules.

"At the same time it is a message to everyone that no one can escape [the testers].”

Natasha Mayers (pictured), who finished second on the podium to take St Vincent and the Grenadines’ first athletics medal of the Games, will be elevated to gold if Oludamola is stripped of the title, with England’s Katherine Endacott getting silver and Bertille Delphine Atangana of Cameroon bronze.

Organisers have conducted over 950 of 1,500 doping tests since the start of the Games, Fennell said, with Oludamola’s the first positive in more than 700 results.

However, The Athletics Federation of Nigeria (AFN) has jumped to the defence of Oludamola.

"She took medication for her toothache and we strongly suspect that it was that which led to her failed drug test," said AFN President Solomon Ogba.
