'Watch what I'm going to do' - NYC gunman announced before attack
US police say the man who shot dead two New York police officers told members of the public "watch what I'm going to do" shortly before the attack.
Twenty-eight-year-old, Ismaaiyl Brinsley, had a history of violence and mental instability.
Candlelit vigils have been held in New York in memory of the two officers, Liu Wenjin and Raphael Ramos.
Brinsley shot them as they sat in their patrol car in Brooklyn before running into a nearby subway station and reportedly shooting himself.
He had posted messages on social media saying he would kill police officers in retaliation for the death of Eric Garner, a black man who died when white police officers arrested him.
The killings come at a tense time, with nationwide protests over the deaths of unarmed black men at the hands of police officers.
