The In Da Club hitmaker came under fire over the weekend (01May16) after posting a video of 19-year-old janitor Andrew Farrell pushing a cart of cleaning supplies through Cincinnati/Northern Kentucky International Airport on Instagram, and when the employee failed to respond to the musician, 50 accused him of being high on drugs.

The video went viral before 50 Cent took it down after realising he had been insensitive when Andrew's stepfather, Ken Kramer, revealed the teen suffers from social anxiety disorder and hearing impairment.

50 Cent has since apologised, stating, "It was certainly not my intent to insult him or the disability community (sic), which is a source of great strength in America. I have apologized personally to him and his family. While the incident at the airport resulted from an unfortunate misunderstanding, I am truly sorry for offending the young man."

According to TMZ.com, Farrell's attorney says the family now wants 50 Cent to donate $10,000 to Autism Speaks, an organisation dedicated to research and spreading awareness of the neurodevelopmental disorder.

And now, Shkreli, who was widely condemned for raising the price of AIDS medication from $13.50 (£9) to $750 (£500) per pill last September (15), is hoping to earn karma points by donating the hefty amount 50 Cent has yet to offer the charity.

Shkreli tells TMZ he decided to reach out to Farrell's family because he has close friends and a family member suffering from autism.

Shkreli, who also hit headlines last year (15) after paying millions at auction for the Wu Tang Clan's one-of-a-kind album Once Upon a Time in Shaolin, is currently facing securities fraud charges in U.S. federal court related to his former post as the CEO of Turing Pharmaceuticals.
