A man in his 40s was allegedly stabbed in the neck and thrown from his wheelchair during a struggle with a woman who forced her way into a home in Thornlie, in Perth’s southeast.
Another resident, a woman in her 50s, was also allegedly assaulted in the armed robbery that 7NEWS understands was a Facebook Marketplace meetup on Saturday morning.

The alleged female offender first arrived at the home on Bremer Pl and, after a short conversation at the front door, allegedly forced her way inside, armed with a bladed weapon, WA Police said.
While she was inside, two other men — one allegedly carrying a weapon believed to be a pickaxe — also entered the residence.
The male resident was stabbed in the neck and the female resident sustained an arm injury, police said.
One of the residents sought help from a neighbour about 10.55am, and responding St John WA paramedics took both of the injured residents to hospital.
The alleged offenders fled the scene, and have all been described by police as appearing to have olive skin with medium height and build.
The female was, at the time of the incident, wearing blue jeans, a brown and white striped long-sleeved shirt and a black cap with a motif, or writing, on the front, WA Police said.
Any witnesses or anyone with relevant information about the incident are urged to contact Crime Stoppers.
