Members of the Sarnia Police Service Vice Unit, as part of an ongoing investigation, executed a search warrant for drugs at an address in the 700 block of Devine Street, in the City of Sarnia. Officers from the Vice Unit, along with officers from General Patrol and the Criminal Investigations Branch, made entry into the residence at approximately 8:50 pm on April 5, 2017. Upon entry four individuals were located in the residence and taken into custody. Three females, 35, 45, and 47 years of age, were charged with two counts of possession of a controlled substance, namely crystal methamphetamine and hydromorphone. The three females were released on a promise to appear. The 35 year old female is from Point Edward while the other two are from Sarnia. A 29 old male, from Inwood, was charged with two counts of possession of a controlled substance and also faces charges for two counts of breaching his recognizance. This male was held for a bail hearing. Officers noted that a number of sharps containers were located along with other needles being discarded throughout the residence. This is a significant safety issue for officers when entering a residence such as this. Police are even more so concerned due to the fact that often times these needles are discard into the immediate neighbourhood and become a risk to all if an individual is poked by a needle. We ask people not to touch any found syringes but instead contact the police and we will discard them for you. The police are also reminding the public that if they observe an increase in foot traffic to a specific residence, with people coming and going throughout the day and night, they can contact Sarnia Lambton Crime Stoppers with the information. The information will then be forwarded to police and if possible be used as part of an investigation.
