London tuition fees demo police appeal prompts calls
Police have received more than 50 calls after releasing images of people allegedly involved with violence at last week's tuition fees demonstration.
Fourteen pictures of people the Metropolitan Police wanted to identify in connection with Thursday's central London protest were sent out on Sunday.
A further four images and footage have now been distributed.
A total of 36 people have been arrested in connection with what was the fourth national protest over the issue.
Thousands of demonstrators gathered in Parliament Square on Thursday as MPs voted in favour of plans to allow universities to increase tuition fees to up to £9,000 a year.
Violence broke out as protesters clashed with police and a car carrying the Prince of Wales and Duchess of Cornwall was attacked as the disorder spread.
Police said 34 were initially arrested, all of whom have been bailed, followed by a further two over the weekend.
Charlie Gilmour, the son of Pink Floyd guitarist David Gilmour, was arrested on Sunday morning on suspicion of violent disorder and attempted criminal damage of the Union flag on the Cenotaph.
A 17-year-old boy was arrested later that day on suspicion of violent disorder after handing himself in.
He remains in custody at a central London police station.
Supt Julia Pendry said: "If you have been on one of the recent demonstrations, and been one of the people who have crossed the line from protester to criminal, you need to understand that our team is looking for you.
"In the heat of the moment it can be all too easy to get swept away with the crowd and break the law.
"You need to know that you will be the person held accountable for your actions."
Scotland Yard has started a "major criminal investigation", called Operation Malone, into all the tuition fee protests so far which started on 10 November when students stormed Conservative headquarters in Millbank, and including Thursday's demonstration in Parliament Square.
A total of 176 people were arrested during the four demonstrations.
