A man killed this weekend and those arrested in connection with his death all lived at the same hostel.
Bruce Andrew Mortimer, 46, died last night from injuries he sustained in an incident in Nelson's Franklyn Village residential units about 2.30am yesterday.
Franklyn Village owner Liz Harris said staff and residents were devastated after Mr Mortimer's death.
"This is a dreadful thing to happen for our community."
Ms Harris said the village's manager was away this weekend so she flew up from Christchurch to support staff.
