Sprinter Brian Mariano has been given a preliminary suspension after failing a drugs test during an international event in France last month, the Dutch athletics association said on Tuesday.

Mariano was tested after the event on February 6 in Mondeville. The association did not say what illegal substance Mariano is said to have taken. His suspension will last until the outcome of a second test is known and the board decides what to do next.

Mariano, 31, said in a statement he had no idea how he had come to consume a banned product. ‘It may have been in one of the supplements I ordered online,’ he said. ‘I know that I am responsible for my actions and I accept the suspension.’

Mariano is joint holder of the Dutch 60-metre record with a time of 6.60. He was part of the Dutch sprint relay team which won gold at the European championships in 2012.
