Police say they were initially tipped off in November after approximately 100 garbage bags and plastic containers were found dumped along a driveway on Woodbine Avenue. The bags were allegedly giving off a strong chemical odour. A similar dump was located a month later in December, this time at a property south of Mount Albert Road.
