On Tuesday's Backchat, we're looking into psychiatric care for people with mental illness, after two shoppers were fatally stabbed at a Diamond Hill mall on Friday.
The alleged murderer -- a 39 year old unemployed man without known links to the victims -- suffers from schizophrenia and was receiving treatment at an outpatient clinic.
The following day, a 24 year-old man with a history of psychosis was arrested on suspicion of threatening his neighbours with a pair of knives.
Meanwhile, in another tragedy a mother was arrested on suspicion of killing her three daughters at a flat in Sham Shui Po.
We'll be talking to specialists about how to limit the risk of such incidents occurring in society. And what about the effects of the shocking images circulating online?
After 9:45, we get more from a tour guide on the attraction of the Haw Par Mansion, which is reopening to the public.
Let us know what you think. You can leave a message here on our Facebook page, email us at backchat@rthk.hk, or give us a call on 23388266.
