WINOOSKI — Police in Winooski say a domestic abuse complaint triggered the evacuation of some tenants in an apartment complex after officers suspected there was a drug lab in a bedroom.

The Burlington Free Press reported that Sunday’s lab scare brought about 50 safety personnel, including firefighters and teams trained to handle clandestine labs and hazardous materials.

When police arrived, they said 20-year-old Pan Costa-Mangina of Winooski told them were no problems. But then his mother approached officers and told them he allegedly threatened some people.

Police said they found a gallon-sized ice tea plastic jug on a milk crate, being cooked in the bedroom. It wasn’t immediately known what it was.

Costa-Mangina was jailed on aggravated domestic assault and unlawful restraint charges.
