Kevin Brennan, who lives about 150 metres from the suspect's house,was out walking with his wife and 14-month-old daughter when an officer in an unmarked car told him to go home and stay inside in the basement.

"I heard five shots and it sounded to be from a pretty small-calibregun from where I was."

"Police come up the street now and again,but very seldom do we get stuff like this happening," Cooper said.
