Police in stand-off with armed man

Heavily armed police have blocked off a street in Sydney’s south-west where an armed man is believed to be holed up inside an apartment block.

Officers descended on the suburban street in Ashcroft in the late hours of Thursday night.

Police have cleared Elizabeth Drive and Maxwells Avenue.

It’s understood the armed man is making threats while armed with a gun.

There are reports some witnesses reported the man appeared to have a pipe bomb or explosive device with him.

Roadblocks in surrounding streets have been put in place and residents are advised to stay inside.

Elizabeth Drive has been closed in both directions and motorists should avoid the area if possible.
