Five more teenagers have been arrested at the house where police were pelted with bottles when they tried to contain a 150-strong mob.
Police were called to the Wellington St, Hamilton house at 1am on Saturday morning and again at 11pm the same day after neighbours complained to Hamilton City Council noise control.

Hamilton Police Senior Sergeant Stephen Ambler said last night there was only 50 people at the party compared to 150 the previous night, but police were again pelted with bottles as they assisted council noise control staff to seize a stereo.
Mr Ambler said the situation was too dangerous on Friday night to take the stereo but residents had had enough of the noise last night.
