Britain's historic Boat Race was dramatically disrupted when a protester swam across the River Thames, before Cambridge claimed a controversial victory over rivals Oxford.
Trenton Oldfield caused a half-hour hiatus in the race between England's two oldest universities, which is in now its 158th year, in a stunt that will raise security questions ahead of the Olympics and the queen's Diamond Jubilee.
After the race was restarted there was fresh chaos when the two crews clashed and one of Oxford's oars snapped off.
The team's desperate, abortive efforts to recover caused one of their rowers to collapse as they crossed the finish line, although Oxford boat club president Karl Hudspith later said he "is conscious and will hopefully be OK".
Hudspith blamed the protester for Oxford's defeat, saying in a Twitter message: "My team went through seven months of hell, this was the culmination of our careers and you took it from us."
Oldfield was arrested and was later charged with an offence under the Public Order Act, police said.
