Calgary police say there will be no charges laid in an Idle No More protest held Jan. 12 that blocked traffic on the 14th Street bridge near downtown.

About 75 people marched seven kilometres from Nose Hill Park to the bridge, where protesters waved signs and chanted while blocking traffic for several hours.

The incident was peacefully resolved, but police decided to investigate whether charges were necessary.

The decision to not press charges was made in consultation with the Crown prosecutor's office, say police.

The Idle No More movement, which began in November and quickly spread, was largely a protest against Bill C-45 — the federal government's omnibus bill that proposed changes to the Navigable Waters Protection Act as well as the Indian Act.

The protests later turned into events to raise awareness of native issues.
