Otago University Students Association urging students not to use social media to ignite dangerous rumours

19-year-old Sophia Crestani died and two other people were seriously injured when a party on Dundas Street became overcrowded on Saturday night.

In a Facebook statement, O-U-S-A asks people to respect the police investigation and not use social media as a tool to share stories or further traumatise people.

It's extending deepest sympathies to the victim's family and friends - and is urging students to seek support.
