"So it does seem like gender-based violence, misogynistic violence is growing, or has become more and more concerning in the last few years."Psychologist Leona Deakin started her career with West Yorkshire Police. She says it is easy to think these ideas are "silly" until they become violent reality.

"If we're not in a community, or close to a community and their beliefs, then it's easy to think it's a small group of people being a bit silly until something like this happens. Then that makes us all take a closer look," she says."There is a community out there for men who feel they are isolated or rejected by society and more immediately by women and girls."Some of these men call themselves "incels", which stands for "involuntarily celibate".

Ms Deakin explains why this ideology can be attractive."There is a theory in that community that 80% of women are only attracted to about 20% of men, and those men are highly attractive and usually very wealthy.

"So if you're a young man who sees himself as not so attractive, and doesn't have much money or the capacity to earn much money, then you start to feel quite aggrieved.
