She claims not to have been rewarded for her gold medal winning exploits in the F40 category at September's Games in the Brazilian city.

Onye, also a gold medal winner at the 2015 World Championships in Doha, claims she is no longer "proud" to represent her nation.

"I am extremely angry with sports issues in this country," the 32-year-old told the News Agency of Nigeria.

"It seems that the Government is not concerned about what happens to athletes.

"I train without the help of the Government and I attend international competitions and win medals for the country because I love Nigeria.

"But, I have had enough because there is nothing to show that my country loves me after what I have achieved - I am not proud of my country.

"When I win laurels, my name and that of Nigeria is called, the national anthem is sung and this to me is patriotism."

Nigeria claimed eight golds in a 12 medal haul at Rio 2016.

Onye, who broke the world record with a best effort of 8.40 metres in her final, was the only athletics winner, however, with the seven other gold medals all coming in powerlifting.

She claims to now have no interest in competing at next year's World Championships in London.

It is presumed that she will instead focus on a fledgling acting career.

"As an Olympian and two-time world record holder, people tell me that I am supposed to be driving my own car, when they see me on the streets, they mock me to my face," Onye added.

"Therefore, I have made up my mind to stop going for training because there is no need to continue with what is not appreciated, I cannot be wasting my time.

"Do you know how long I have been enduring; it is not easy to go for training virtually five days in a week for a year without any assistance? 

"Do you know how it feels like to be a champion who cannot boast of anything? 

"I choose not to look at my disability by engaging myself meaningfully. 

"This time, I will rather be a truck pusher than be a superstar for nothing."

Nigerian authorities have not yet responded to her comments.
