A protester who disrupted this year's Oxford v Cambridge Boat Race by swimming into the path of the crews has been jailed for six months.
A protester who disrupted this year's Boat Race by swimming into the path of the crews was found guilty today of causing a public nuisance.
A swimmer who managed to halt today's Boat Race has been arrested on suspicion of a public order offence.
Royal Marines will be stationed in inflatable boats along the length of the Boat Race course tomorrow to ensure the event is not disrupted by another protester in the water.
Last year's race had to be halted when Trenton Oldfield swam into the path of the two crews and narrowly avoided being struck by an Oxford oar as he looked to sabotage an event he regarded as elitist.
Oldfield was released from prison in December having served seven weeks of a six-month sentence after being found guilty of causing a public nuisance.
Cambridge won the restarted race.
Trenton Oldfield would not be deterred from protesting again, his wife, Deepa Naik, has said.
Speaking outside court, she attacked Britain and London as being brutal and deeply divided.
She said: "Trenton has spent his adult life working on these issues and his direct action protest on the 7th April 2012 was a natural extension of his everyday work.
"Trenton's protest was a reaction to an increasingly brutal business, media and political elite."
She added: "Great Britain has convinced many it is the home of democracy and the gauge of civilisation. Anyone living here today knows Britain is a brutal, deeply divided, class-driven place."
Trenton Oldfield, who disrupted the Oxford-Cambridge Boat Race, jailed for six months by judge who says he was prejudiced against the Oxford and Cambridge University boat race teams.
