Rapper 50 Cent has come under fire after posting a video of himself confronting a janitor who has autism at a Cincinnati airport and accusing him of being on drugs.

The 40-year-old, real name Curtis Jackson III, can be heard in the footage ridiculing the man as he follows him through the airport.

He says: “Look at him. What kind of s*** do you think he took before he got to work today?

“He high as a m********** right here in the airport. The new generation is crazy.”

The rapper has since deleted the video from his Instagram account after an online backlash.

The parents of the worker, Andrew Farrell, said he has mild autism and deals with social anxiety.

Father Ken Farrell said seeing the footage felt like a “slap in the face”.

He told WKRC: “It hurts to watch that, it’s painful.

“You come up and you start talking to a kid you know nothing about. That’s not fair. That’s a slap in the face.”

His mother, Amanda, called for an apology from the In Da Club singer.

She told the TV station: “Personally, I think the guy was mad. Andrew didn’t know who he was right away and he ignored him and he did his job and went about his business.

“I think he was mad and offended that someone didn’t flock to him.”

50 Cent has yet to comment on the video.
