Lance Armstrong denied having "misbehaved" during a random drugs test conducted by the French anti-doping authority last month.

The seven times Tour de France champion was requested, while training in France, to provide urine, blood and hair samples to a tester from the French Anti-Doping Agency (AFLD).

The AFLD said this week the 37-year-old American behaved strangely when the tester asked him to provide the samples and it sent a report to the International Cycling Union (UCI).

The UCI said it could not rule on the matter since the test, which proved to be negative, was commissioned by the AFLD.

Armstrong, who described reports in France that he had "misbehaved" as outrageous, said he just wanted to have the tester's ID checked before complying with the request.

"I had never heard of labs or governments (the AFLD reports to the French government) doing drug testing and I had no idea who this guy was or whether he was telling the truth," the Astana rider said in a statement.

"We asked the tester for evidence of his authority. We looked at his papers but they were far from clear or impressive and we still had significant questions about who he was or for whom he worked.

"I was there with (team manager) Johan Bruyneel and two other people. We told the tester we wanted to check with the UCI to confirm who he was and to make sure he wasn't just some French guy with a backpack and some equipment to take my blood and urine."

It was Armstrong's 24th test since he resumed his career after 3-1/2 years in retirement.
