EASTENDERS will finally reveal how its character Lucy Beale was killed in a flashback episode as part of the show's 30th anniversary week.

The episode, to be screened on BBC One next month, will bring an end to the "whodunnit" story which has gripped viewers since Ian Beale's daughter was murdered on Good Friday last year.

Fans will not only learn how Lucy met her death but also why the murder was carried out, she added.

Several cast members will reprise their roles, including Hetti Bywater, who plays Lucy Beale.
