Woman removed from parliament over threats

A woman who shouted threats against the prime minister during question time has been escorted from parliament's lower house.

Jan Olson was removed from the public gallery by security guards on Tuesday after shouting "and we're coming after you!" in the chamber.

Ms Olson was later met by a group of Australian Federal Police officers outside.

She told AAP her threat was centred on Tony Abbott and related to documents she was denied under Freedom of Information about his birth certificate and legitimacy as prime minister.

The disturbance did not disrupt proceedings but comes amid heightened security at parliament house in response to the terror threat level.
