LONDON - Another case of doping has struck the 2012 London Olympics.

Uzbek gymnast Luiza Galiulina is the second athlete to test positive for a banned substance since the games began on Saturday.

She has been suspended from participating in the tournament.

Galiulina failed the drug test on Friday just four days before the start of the women's artistic gymnastics competition.

The substance known as diuretic furosemide can be used as a concealing agent to disguise the use of other drugs.

It is the second case of doping at the Games after Albanian weightlifter Hysen Palaku tested positive for steroids.

Pulaku tested positive for a banned steroid, stanozolol and that a "B" sample confirmed the result.
