Five anti war protesters have been arrested after a demonstration at the Auckland district court.

It is believed the protest, involving around 20 Global Peace and Justice members, was staged outside a courtroom where a protester who was arrested at a weekend demonstration was due to appear.

The same group were involved in a protest outside the United States consulate in downtown Auckland on Saturday, when four arrests were made.

Following that protest a complaint was laid against police after a sergeant used a two-handed throat hold on a teenager.

The grip was used on the 16-year-old as he tried to hold the doors of a police car open to stop them driving away after arresting another protester. The teen was not arrested.

The five people arrested on Monday have been charged with trespass.
