Vienna police say they have discovered a plantation with more than 700 marijuana plants at a warehouse close to a police dog center.

Police say one of their dogs caught a whiff of the plants in the Austrian capital's Floridsdorf district on Friday morning. Officers then saw a man taking a hose into the warehouse and searched the premises, finding 734 cannabis plants.

They said in a statement Saturday they also found 32 sacks stuffed with deep-frozen marijuana and a bag full of dried marijuana at the 27-year-old suspect's apartment.

Police say the man is denying wrongdoing. Spokesman Roman Hahslinger told the Austria Press Agency the suspect comes from outside Vienna and might not have known that a police facility was nearby.
