It’s understood the woman – believed to be aged in her 30s – was allegedly stabbed by a man she knew on the sixth floor of the Quality Hotel Ambassador Perth just after 9.30am this morning.
A man has been arrested.
Detective Senior Sergeant Michael Foge said a weapon was involved in the incident, which he said happened “inside one of the rooms and then migrated into the corridor”.
Local Jeremy Grazziadelli described hearing the “wail of sirens” this morning.
“As they came out they had a gentleman on the gurney, he was covered in quite a bit of blood. They were doing CPR,” he told 9News.
Some guests who had already left the Adelaide Terrace hotel weren’t allowed to return, while some arriving guests weren’t allowed to check in.
Investigations continue.
