The identity of a man charged with the random stabbing of four people on Auckland's North Shore remains secret while he undergoes treatment for psychosis.
The 41-year-old allegedly stabbed four people in the quiet Murrays Bay and Mairangi Bay suburbs on June 23 before passersby took him down in what police have called a show of extreme bravery.
He faces four counts of wounding with intent to cause grievous bodily harm, and two charges of assault with a knife.
He is yet to enter a plea.
