The man who was last year cleared of the murder of television presenter Jill Dando is seeking damages of up to £100,000 for libel, according to the Guardian.
The publication reported that Barry George, who served eight years in jail before being cleared, is suing Mirror Group Newspapers (MGN) - which owns the Daily Mirror - over a number of articles that ran in the People, the Sunday Mirror and on mirror.co.uk.
He alleges the articles were libellous, misused private information and complained of harassment. The high court writ claims the newspapers published details of his movements - including stays at a hospital and a hotel - and a series of photographs.
Mr George is also seeking an injunction from the high court which would ban the newspapers from repeating the claims.
MGN is owned by Trinity Mirror, which is one of the largest newspaper publishers in Britain. It has nine printing sites and its portfolio includes 400 digital products and five newspapers with national distribution.
