A doctor at the centre of the 'mystery package' sent for cyclist Sir Bradley Wiggins has no record of his medical treatment at the time, MPs have heard.
Team Sky and British Cycling's record-keeping has been strongly questioned.
Former Team Sky medic Dr Richard Freeman had a laptop containing medical records stolen in 2014, said UK Anti-Doping chief Nicole Sapstead.
"No one has any recognition of what was in the package," she told the Culture, Media and Sport Select Committee.
Freeman, who received the package on behalf of the team in 2011, missed the hearing on Wednesday because of ill health.
In December, Team Sky boss Sir Dave Brailsford told the committee that the package contained an over-the-counter decongestant, Fluimucil.
