Police have released pictures of people they would like to speak to after recent protests in London.
Thousands of demonstrators took the streets of the capital between November 10 and December 9 against the coalition government and the proposed rise in tuition fees to a possible £9,000 a year.
Six images were released of people involved in the November 24 demonstration, and there are seven pictures of protesters in Parliament Square on December 9.
Officers also reissued images of 11 people they wish to speak to in connection with the disorder on November 10.
A spokesman said: “The Metropolitan Police launched a major criminal investigation into the student disorder seen across London between 10 November and 9 December.”
