First call of my daughters shift today was 'stabbing in Thamesmead tower block, police on scene'. Not an uncommon call for that area.
She got there to find it was accidental. A mains powered smoke alarm had been beeping and the victim decided to cut the cable feeding it. It was live and he used metal scissors!
The electric shock caused him to react violently and he stabbed himself in the leg with the scissors - twice!
