There has been a serious police incident on Brisbane’s south side, where there is a heavy police presence and at least one street has been blocked off.

Officers and paramedics were called to an address in the Mt Gravatt-Holland Park area a short time ago.

Witnesses have reported hearing gunshots.

Images from a media helicopter show part of the suburb in lockdown and a street cordoned off with dozens of police in the emergency zone.

More to come.
