A MAN who brought parts of Parramatta to a standstill for 11 hours, after claiming to be armed with a bomb, was arrested by heavily armed police in a dramatic raid last night.

The man's daughter, who was with him throughout the siege, reportedly shouted ''don't hurt my dad!'', after the tactical operations unit entered a barrister's chambers in George Street where they had been barricaded since 9am.

The man will face Parramatta Local Court today after being charged with various offences.

The Assistant Commissioner, Denis Clifford, said police forced their way into the office building about 8pm after negotiations broke down.
