The family of a schoolboy stabbed to death in a busy London Underground station have spoken of their loss.
Sofyen Belamouadden, 15, was chased into the busy Tube station and hacked to death with knives last week.
His aunt Souad Ghailan said her life was "empty" since the death of her nephew.
A teenage girl was arrested on Monday in connection with the stabbing as 12 youths appeared in court charged with his murder.
Metropolitan Police investigators held the girl suspect and three more teenage boys during a series of raids in south London.
The move brings the total number of people arrested over the attack at Victoria during last Thursday's rush-hour to 24.
