Another Knife Attack

A woman of 34 went around the concourse of a station in Kanagawa randomly slashing at people. She cut 7 men who sustained light injuries.
A student aged 21 managed to pin her down to the floor and call the police. The small pic (the only one I could find) shows the woman in a green shirt being pinned to the floor.

She said that she wanted to kill her dad but couldn't. She also said that she wanted to die and might as well take some people with her...
Looks like the knife-anybody thing is getting popular over here...

Great that the student got to her before she could kill people. Reminds me of when I was a wee lad back in London. I saw a shifty looking guy at night who I kept an eye on as I walked. He snatched the bag of a woman and done a runner. I shouted "Oi!" in my cockney accent and ran after him.
He dropped the bag after a while and leaped over a tall fence - looks like he done it before. I decided not to pursue any further, picked up the bag and handed it back to the woman. She was fine and I continued on my way home.
Have you been involved in any crime preventing shenanigans?
