VIDEO | Campaigner tries to effect citizen's arrest on Tony Blair in Dublin

An Irish anti-war campaigner has attempted to make a citizen's arrest on former British prime minister Tony Blair over alleged war crimes.

Activist Kate O'Sullivan managed to get through tight security to confront Tony Blair as he held a book signing in Dublin.

The 24-year-old from Cork claims to have queued for 90 minutes and went through airport style security - handing in all her belongings and going through a metal detector - before she attempted to arrest Mr Blair.

She says the former Prime was blasé about her accusations: "He didn't say anything, He just signed the book, and nothing else."

Earlier, shoes and eggs had been pelted at Mr Blair as he arrived at the bookshop on O'Connell Street in Dublin city centre.
