Man charged after frightening Canberra siege

A man who sparked a lengthy police siege, after allegedly assaulting a man and barricading himself in his apartment, has been denied bail in the ACT Magistrates Court.

Police allege 39-year-old Van Long Pham entered the unit and allegedly assaulted the resident with a samurai sword.

Pham believed his friend was conspiring with bikies to have him killed.

At one stage, he brandished the 80-centimetre sword and allegedly said, "I'm not going to stab you, I'm just going to give you a poke".

Residents of the unit block were evacuated after police noticed a strong smell of petrol.

Parts of Monaro Crescent were also closed off during the siege.

Pham was eventually taken into custody and charged with assault causing bodily harm, forcible confinement, and possessing an offensive weapon with intent.

He has pleaded not guilty to all charges.
