“Our enquiry continues to be led by a nationally accredited homicide Senior Investigating Officer, supported by a dedicated joint police and HSE Major Incident Room consisting of detectives, HSE inspectors, a digital evidence review team, disclosure officers, technical experts and our family liaison officers who maintain regular contact with the families in order to support and advise them on the progress of the case.

Oxford Mail:

“We maintain close contact with the Crown Prosecution Service through a dedicated lawyer and a disclosure barrister to give independent oversight on the investigation.

“On this day when we remember those who died and those who were injured, I would like to be clear that the scale and complexity of this investigation will not be a barrier to us obtaining the answers that the families so desperately deserve.”
