Police in Braintree, Massachusetts, say their investigators found four homes believed to be used for an illegal marijuana production operation, officials said.
An investigation into a marijuana grow house in Braintree led the discovery and the arrest of three people.
One of the homes allegedly involved in the operation was in Braintree, another in Westford and the last two in Quincy, according to the Braintree Police Department.

Officials executed search warrants on the four homes on Wednesday and seized enough pot to meet the trafficking weight element of Massachusetts drug laws. Several marijuana plants, packaged marijuana and tools used to help plants grow were found on the sites, according to police.
Xu Feng Wang, 30, of Boston was arrested at the Braintree home and charged with trafficking a class D substance and conspiracy to violate drug laws. He is expected to be arraigned on Thursday. It is unclear if Wang has an attorney.
A 48-year-old Quincy man and 23-year-old Quincy woman were also charged with trafficking a class D substance; however, their names were not immediately released. It is unclear if either has an attorney.
Authorities warn these types of marijuana grow operations could cause public safety hazards since dangerous chemicals and faulty wiring are commonly found in these sites. These conditions can create an environment for black mold to flourish, Braintree police said, and that often, homes used for such an operation are not lived in.
Braintree police added that board of health officials have since condemned the home in Braintree due to "uninhabitable conditions."
