A 23-year-old man suspected of throwing a fire extinguisher at police from a roof during this week's student fees protest has been released on police bail.
The student at Anglia Ruskin University, Cambridge, was arrested on Friday after police officers scoured footage of Wednesday's riot which saw protesters storm Millbank Tower where the Consertavie Party has its HQ.
The man, originally from Reading, Berkshire, was held on suspicion of violent disorder and questioned at Parkside police station in Cambridge before his release on bail late on Friday night.
A Scotland Yard spokesman said: "He has been bailed to return to a London police station pending further inquiries."
Police Federation representatives have called for the person who flung the empty metal fire extinguisher from the roof of Millbank Tower to be charged with attempted murder.
Senior officers said it narrowly missed injuring two territorial support group officers, brushing down the back of one and hitting the knees of another.
The incident was one of the defining moments of the four-hour stand-off after a breakaway group of students attacked the Millbank office complex.
Up to 50 demonstrators smashed windows, discharged fire extinguishers and threw debris from the roof of the building.
Some student activists have now begun fighting a rearguard action amid widespread condemnation of the violence and fears of further trouble on November 24, the day it is widely believed that ministers will vote on the tuition fees rise in the Commons.
Meanwhile, an internal inquiry into why police did not effectively plan for the possibility of violence, ordered by Met Commissioner Sir Paul Stephenson, is expected to be completed within days.
