AAP/NIRS – Protesters who shut down Question Time in Parliament House yesterday have returned to parliament this morning.

Two people have scaled the building’s front wall and unveiled a banner reading ‘Close the bloody camps now.’

Twelve others have waded out into a pond in the complex’s forecourt, holding placards with slogans such as ‘Justice for refugees.’

Question time was suspended yesterday after about 25 protesters began yelling from the public gallery and superglued their hands to the rails.

Liberal frontbencher Christopher Pyne has called for an investigation into yesterday’s protest.
