A leaky roof led police to a major marijuana bust inside a house in Covina.
Early Wednesday morning, the owner of a home in the one hundred block of Casad Street went to check on the roof that had leaked during rainstorms in the past.
When the tenant answered the door the owner noticed the smell of marijuana coming from inside.
The owner called police. When officers arrived they discovered 99 plants growing inside the residence.
The tenant was arrested at the scene.
