Munich massacre: Teen loner planned gun attack for past year

A teenager who killed nine people and left 27 others wounded in a shooting rampage in Munich was a withdrawn loner who had been planning the attack for up to a year, German authorities said.

Two young women mourn beside the Olympia shopping centre in Munich yesterday.

Officials said the German- Iranian, aged 18, identified only as David S due to German privacy laws but named in some media reports as Ali Sonboly, had been a victim of bullying, who suffered from panic attacks set off by contact with other people.

The teenager had been seeing a doctor for treatment over a number of psychiatric problems, starting in 2015 with in-patient hospital care, followed up with out-patient visits.
