Alan Fonteles, a gold medalist in the 200-meter T44 competition at the 2012 Paralympic Games in London, was involved in a traffic accident while driving under the influence of alcohol in Belem, the capital of Brazil's Para state, but was not injured, a transit police spokesman said.

Fonteles and four other people were driving in the Belem metropolitan area on Saturday when he lost control of his vehicle and rear-ended a bus, transit police spokesman Germano Garcia told the Globo network.

The paralympic athlete showed signs of being intoxicated when he was questioned by officers, Garcia said.

Two of the people accompanying Fonteles were transported to a hospital, the police spokesman said.

A field sobriety test found that Fonteles had a blood alcohol level of 0.22, a reading that qualifies as a serious traffic infraction and is punishable with a driver's license suspension of 12 months under Brazilian law, Garcia said.

Fonteles, who sustained chest and arm injuries in the accident, said he fell asleep at the wheel due to exhaustion. EFE
