A three-year-old girl was seriously injured late yesterday when she fell off a swing which has been temporarily set up under a dome in St George's Square, Valletta.
The accident happened at about 8pm.
The girl was accompanied by her parents at the time.
She is being treated in hospital.
The set of swings was set up for the Mata International Arts Festival as an instinctive mode of entertainment to create an interactive sound installation.
Each swing is equipped with a motion sensor so that music is triggered through the swinging action.
Different instruments are assigned to eight swings so that the whole structure functions like a music ensemble that is brought to life through the interactive engagement of the public.
