Brazilian prosecutors are requesting the imprisonment of a man who ran into dozens of bicycle-riding activists.

Prosecutors Eugenio Amorim and Lucia Callegari say in a statement they have asked for the preventive detention of Ricardo Jose Neis on charges of attempted homicide.

The statement was posted Tuesday on the website of the prosecutor's office of Rio Grande do Sul state.

Neis sped his car through a pack of more than 100 pro-cycling activists in the city of Porto Alegre on Friday. At least 40 were injured, though nobody was killed.

The man tells police the cyclists were beating on his car and threatening him. The cyclists, deny that — and the lead police investigator in the case calls that scenario "fanciful."
