Five years ago two 24-year-old students were set upon by two gangs of youths on the same bridge and thrown into the Thames. Tim Baxter, 25, and friend Gabriel Cornish, 24, were beaten unconscious on the footbridge then lifted over the 4ft rail and thrown into the river. Mr Cornish survived, but Mr Baxter's body was discovered a day later. Six people, aged between 15 and 21, were convicted in April 2000 of murder and attempted murder and jailed for life.
