Thames protester 'could have died'

A protester who swam into the Thames to disrupt this year's Boat Race could have been killed, four-time Olympic gold medal rower Sir Matthew Pinsent told a court.

Sir Matthew, who was assistant umpire during April's race, made a written statement to police just hours after Trenton Oldfield, 36, was plucked from the path of the speeding Cambridge and Oxford boats.

Oldfield, of Myrdle Street, east London, denies causing a public nuisance but admits swimming in the path of the crews. London's Isleworth Crown Court heard that Sir Matthew was immediately behind the university crews on a launch with umpire John Garrett.
