State inspectors found more than 600 marijuana plants growing behind a Connecticut day care center last week, and police say arrests are forthcoming.

Police were called to a home day care center in West Haven on Friday after inspectors discovered the plants during a routine inspection.

Sgt. David Tammaro said the marijuana plants were enclosed by a recently installed wooden fence in the backyard of the home. He saidthe plants were 6 to 10 feet tall with an estimated street value of more than $1 million.

A spokeswoman for the state Office of Early Childhood said the day care center's license was suspended following the inspection, but the action was unrelated to the police investigation.

State records show the house had been a licensed day care center since 1995.
