(Las Vegas, NV) — A marijuana grow house bust has become the largest ever in Metro Police history.

Authorities seized nearly 1500 plants with an estimated street value of $4.5 million Wednesday night, from a rental house near Desert Inn and Fort Apache roads.

SWAT officers became sick from the fumes and had to use hazmat suits.

Two people were arrested, and are under investigation for possible links to other Las Vegas drug operations.
