Police probe house fire drug link FIREFIGHTERS have discovered what is believed to be drug equipment after a house caught fire in Melbourne's northwest last night. CFA spokeswoman Jenny Clow said a neighbour alerted firefighters to the blaze on John Paul Drive, Hillside, after hearing a smoke alarm at about 11.05pm. Five crews from the CFA and MFB attended the one-storey house, which was tightly locked up. "There were shutters on the windows and security doors," Ms Clow said. It took crews about 15 minutes to put out the blaze, which partially damaged the house. Ms Clow said no one was inside the house to her knowledge. Victoria Police spokeswoman Melissa Seach said last night investigators would have to wait to see if the equipment found at the house was a hydroponic set-up before enquiring further.
