A 43-year-old Japanese player in a virtual game world became so angry about her sudden divorce from her online husband, she logged on with his password and killed his avatar.
She is now being held in a real-world prison on suspicion of illegally accessing a computer and manipulating electronic data.
While police have not yet formally charged the woman, she could face up to five years' jail if found guilty.
Police said the piano teacher used her online husband's ID and password to log onto the online game Maple Story to carry out the virtual murder.
They did not believe she had plotted any revenge in the real world.
in japan they have sweat shop style places were people are paid by say the english and americans to build up characters on games like world of warcraft so they gain extra strength etc etc (sad i know!) that could have costs him money i guess... but thats insane!
