The Telekom Affair – In May 2007, several former riders admitted to using banned substances (including EPO ) while riding for the team in the mid-1990s, including Erik Zabel , Rolf Aldag , Brian Holm ,  Bjarne Riis ,  Bert Dietz , Udo Bölts and Christian Henn including the seasons in which Riis and Jan Ullrich won the Tour de France.  Team doctors Andreas Schmid and Lothar Heinrich also confessed to participating and administering banned substances. The latter was Team Telekom's sporting director until 3 May 2007, when he was suspended following allegations published in former team member Jef d'Hont 's book. 
The sport of pigeon racing is alive and well in New York City — and is rife with illegal gambling, the killing of unwanted birds and abusive training methods, People for the Ethical Treatment of Animals alleges.
PETA announced today it conducted a 15-month undercover investigation into pigeon racing by infiltrating the Bronx Homing Pigeon Club and other similar organizations around the country. As part of their covert pigeon probe, PETA even found that performance-enhancing drugs are used on the helpless birds.
The organization found that the birds are often forced to race for distances up to 600 miles, and that 60 percent of birds in those races typically succumb to such things as extreme weather and exhaustion, or fly into electric lines and are killed.
Even those that survive the race are not treated well, PETA alleges. Many birds that make it home but fail to win their owners cash are then suffocated, drowned or decapitated, according to PETA. The group called on the New York Attorney General’s office and the New York Police Department to look into the pigeon club.
