Six people were arrested on Sunday evening after a man in his 60's was beaten and seriously injured in N.D.G.
The man suffered a fractured skull in the attack inside an apartment building on Grand around 11:30 p.m.
Witnesses say the man had gone out into a hallway to complain about noise when he was attacked.
A passerby later found the man lying outside in the snow, and called 911.
Four men and two women between the ages of 25 and 30 were arrested.
