Jonsson returned a positive test for prednisolone and prednisone in a urine sample provided on April 27 of this year.

He provided the sample after competing at the Szczecin 2017 World Shooting Para-sport Grand Prix in Poland.

The substance is included on the World Anti-Doping Agency 2017 Prohibited List under the category of glucocorticoids and is prohibited in competition.

However, following notification of the positive test, Jonsson provided sufficient corroborating evidence to explain how the substance entered his body.

He also explained that the substance was being used for a medically justified reason although his Therapeutic Use Exemption certificate was not valid at the time of the test.

Following analysis of the evidence, the IPC was satisfied that he did not consume the banned substance intentionally.

In accordance with the IPC Anti-Doping Code, a suspension of one month was imposed on Jonsson from August 16 to September 16.

The Swede's results in Szczecin have been disqualified including forfeiture of any medals, points and prizes.

Jonsson won the 10 metres air rifle standing mixed SH2 competition in the Polish city.

He also finished in eighth position in both of the 10m air rifle standing SH2 and 10m air rifle prone SH2 competitions at the Rio 2016 Paralympic Games.
