SYDNEY (AP) — Police have identified the assailant who stabbed six people to death at a busy Sydney shopping center before he was fatally shot by a police officer.

New South Wales Police said Sunday that Joel Cauchi, 40, was responsible for the Saturday afternoon attack at the Westfield Shopping Centre in Bondi Junction, in the city’s eastern suburbs and not far from the world-famous Bondi Beach.

NSW Assistant Police Commissioner Anthony Cooke told reporters at a media conference on Sunday that Cauchi suffered from yet unspecified mental health issues and police investigators weren’t treating the attack as terrorism-related.

“We are continuing to work through the profiling of the offender but very clearly to us at this stage it would appear that this is related to the mental health of the individual involved,” Cooke said.

“There is still, to this point... no information we have received, no evidence we have recovered, no intelligence that we have gathered that would suggest that this was driven by any particular motivation - ideology or otherwise,” he added.
