TORONTO - Toronto police have released security camera images of two men they say are persons of interest in the shooting death of Hou Chang Mao.

The father of two was caught in crossfire last month near a busy market in Toronto's east end, where he was stacking oranges on an outside display.

Police say the two men were seen leaving the area on around the time Mao was killed.

Mao was the second innocent bystander killed this year and is Toronto's third homicide of 2008.

While more than 100 people were present when the crime took place around the supper hour, police have not been able to identify any suspects.

Mao had lived in Canada for two years and had recently brought his 18-year-old daughter over from his native China to join him and his 23-year-old son.
