BEIJING: The Paralympics suffered its second doping scandal in as many days on Wednesday, with a German wheelchair basketballer kicked out of the event for taking a banned drug contained in hair loss treatment.

A statement from the German National Paralympic Committee said Ahmet Coskun had tested positive for finasteride after a pre-competition urine test on August 23.

The substance is used in a drug against hair loss and is on a list of banned substances, according to the statement.

It said that although finasteride does not enhance performance, it can be used to cover up drugs that do.

"I was thinking about my hair and had no idea that the drug, which is against hair loss, contained a banned substance. I'm very upset. I never intended to do doping," Coskun said, according to the statement.

German chef de mission Karl Quade expressed regret at the news.

"We take the issue of anti-doping very seriously. We've been carrying out an intensive anti-doping campaign for years in cooperation with NADA (the German anti-doping agency)," Quade said in the same statement.

Coskun, 33, who played for Germany in three of Germany's pool matches but not in Wednesday's 73-63 win over Iran, will return home soon, German paralympic chiefs said.

Pakistani powerlifter Naveed Ahmed Butt, 37, tested positive for the steroid methandienone metabolites on September 4, two days before the opening ceremony, it was announced on Tuesday.

Meanwhile, China sat atop the medals table at the end of competition on Wednesday, boasting 24 golds, and once again leapfrogging Britain.

On 21 golds, the British have been boosted by a remarkable 12 track cycling golds, continuing the domination of the sport they showed at the Olympics.

"We're delighted with the British performances across the sports so far and to be where we are in the medals table at this stage is fantastic," said British chef de mission Phil Lane.

In the evening's action, Polish teenager Natalia Partyka stormed to table tennis gold, just weeks after realising her dream of playing in the Olympic Games.

Partyka, the first table tennis player to compete at both the Olympics and Paralympics, beat China's Fan Lei 11-8, 11-4, 11-9 in 23 minutes to successfully defend her Athens crown in her class.

The 19-year-old is one of only two Paralympians who also competed at last month's Olympics, along with South African swimmer Natalie du Toit, who already has two golds out of the five she is aiming for.

"In Athens four years ago it was easy. Here I had much better opponents but I concentrated hard and just played my own game. I have done very well," she said.

Partyka, born with a right arm that ends at the elbow, has proved she can mix it with the top able-bodied players, defeating Singapore's Li Jia Wei, ranked six in the world, at this year's world team championships in China.

More than 4,000 competitors from nearly 150 countries and regions are battling for 472 gold medals in 20 sports at the eye-catching venues used for the Olympics such as the "Bird's Nest" and the Water Cube.

The sports at the Paralympics, which end on September 17, include athletics, swimming, powerlifting, wheelchair fencing and five-a-side and seven-a-side football, as well as the lesser-known goalball and boccia. - AFP/de
