The police who raided the Swiss home of Germany's 1997 Tour de France champion Jan Ullrich on Wednesday did not take DNA evidence from him, chief police officer Herbert Ammann said in a magazine article published Sunday.

Ullrich's home was one of ten private and business addresses raided both in Germany and abroad as he and others are investigated further over connections with Spanish sports doctor Eufemiano Fuentes, the alleged head of a blood-doping ring. In an article in Sunday’s Focus magazine, Amman, however, denied earlier reports that the police had seized DNA samples in the raid.

The 33-year-old German has so far refused to take a DNA test to clear his name and there remains a debate as to whether or not a test can be performed without his permission.

Heidelberg sports lawyer Michael Lehner claims Ullrich is unlikely to have much of a say in the matter as prosecutors try to clear up the doping scandal.

"As the potential guilty party Ullrich does not have the right to decline," Lehner said in the Suddeutsche Zeitung.

Ullrich was fired by his T-Mobile team during this year's Tour de France - which he was barred from racing in when the allegations were made - after a Spanish investigation offered evidence that he was involved in doping.

Ullrich is said to have been given the blood-boosting drug EPO, human growth hormones and steroids by Fuentes but denies knowing the doctor.
