Two 35-year-old men are in custody after 400 marijuana plants were seized at a northwest Harris County house.

Sheriff's authorities say Quoc Linh Ngo and Tuan Anh Vu were arrested Friday after a complaint from a citizen.

Vu already was free on bond after his arrest last year for a similar pot growing operation in the Houston suburb of Katy. Ngo's bond has been set at $630,000.

Officials place the street value of the marijuana at about $2 million.
