The midfielder, 21, made a series of gross remarks between 2013 and 2014, while in Leicester’s academy.
Among them he wrote in June, 2013: “Why are black people so fast? Because the slow ones are in prison.”
A month later, he said: “That has to be the worst advert sums up women’s football to be honest.”
And in August that year, he said: “Sorry but I don’t feel sorry for people who self harm or commit suicide.”
“I’ve learned a lot as a person in my early years as a professional – certainly enough to know that some of the thoughtless comments I have made in the past are both hurtful and offensive”
The tweets were dug up the wake of the Foxes 3-0 win over Arsenal on Sunday, during which he made his first start under new boss Brendan Rodgers.
His account was then deleted shortly after the game.
Choudhury has apologised and says he has matured as a person since the tweets.
He said: “I’ve learned a lot as a person in my early years as a professional – certainly enough to know that some of the thoughtless comments I have made in the past are both hurtful and offensive.
“They do not represent my true beliefs. I’m deeply sorry to anyone I have offended – both at the time and since they’ve been recirculated.
“I’ve grown up a lot since then and learned a lot about life, but I accept that I have to take responsibility for the comments I have made in the past and will be a better, wiser person for it.”
A Spokesman for Leicester said: “Hamza’s approach to addressing the matter and the remorse he has expressed shows the maturity he has developed in the years that have passed since the comments were made.
“He now has a far greater understanding of the impact his words and behaviour can have and is committed to using that influence in the positive, respectful and accepting manner his more recent growth has demonstrated.”
