Nigerian gold medallist Chika Amalaha has been provisionally suspended from the Commonwealth Games after an in-competition drugs test resulted in an anti-doping violation, the Commonwealth Games Federation has announced.

The 16-year-old Amalaha provided an ‘A’ sample on July 25th — shortly after winning the women’s 53kg category — which revealed traces of diuretics and maskings agents.

Amalaha will have a ‘B’ sample tested at a laboratory in London tomorrow.

Commonwealth Games Federation chief executive Mike Hooper said: "We [have] issued a formal notice of disclosure to an athlete following an adverse analytical finding as a consequence of an in-competition test.

“That athlete is Nigerian weightlifter Chika Amalaha who was tested on July 25th. That athlete has now been suspended from the Commonwealth Games in Glasgow.”
