She set an indoor European record at the beginning of 2010: her time of 14:46.44 at the GE Galan - a result later voided - was enough to beat Gabriela Szabo's 11-year-old mark. Despite this achievement, which made her the fifth fastest of all-time over the distance, she finished some 20 seconds adrift of winner Meseret Defar who narrowly missed the world record.[1] This record was later rescinded due to a doping offense.[2]
On 16 January 2013, the IAAF announced that she had been banned from competition for four years until 14 February 2016 due to use or attempted use of illegal drugs, and all her results since August 17, 2009 will be voided. This resulted from irregularities in her biological passport.[2]
