Dog lovers beware - the Bowen Road poisoner is back and has killed at least two animals in the past week.
A dog's body was found in a roadside drain in Wan Chai Gap Road, near Bowen Road, on Friday morning.
It was the first time the poisoner - who has killed an estimated 200 dogs during his two-decade reign of terror - has struck since December 2010.
Another dead dog was found in the same spot yesterday.
Pieces of bait, laced with a black powder believed to be a poison, were found in eight locations in the Black's Link area on Saturday, police confirmed, without giving details of the bait used.
Officers are investigating whether the cases are linked and have stepped up patrols and put up posters in the Mid-Levels area, which has become notorious for dog deaths since the poisoner first struck in 1989.
