In the aftermath of the balcony collapse in which six Irish students died on Tuesday, attention in Berkeley has now turned to the construction of the Library Gardens apartment complex at the centre of the tragedy.

The families of six students killed in a balcony collapse in the US are expected to learn today the early indications of the cause of the accident.
