Three members of staff at a Welsh computer company have been charged with forgery after allegedly sending hoax emails to an exec at a rival company who later killed his 12-year-old daughter.

The trio are accused of sending marketing manager Philip Hall emails that resulted in him going to India on what he believed was a business trip.

This resulted in Hall, who worked for Cardiff-based firm Molecular Light Technology and had a history of mental illness, having a nervous breakdown.

Hours after returning home he stabbed his 12-year-old daughter Emma through the heart as she slept, according to UK press reports. At the time Hall was being treated for manic depression and schizophrenia.

The 41-year-old was cleared of murder late last year by a jury at Swansea Crown Court on the grounds of insanity, but was ordered to be detained indefinitely at a medium secure hospital.

The three charged with the email forgery, who worked at AB Biomonitoring, have not been named. ®
