Four people have been released on police bail and two remain under arrest in relation to the Hamrun building collapse, the police said this evening.
Miriam Pace died on Monday after the residence she lived in collapsed as excavation work was being carried out in an adjacent plot in Hamrun.
The police said that investigations are still ongoing, as is the magisterial inquiry.
Six people were arrested between Monday and Wednesday and are actively assisting the police in the investigation.
