Police in Bridgeport are investigating reports of illegal activity in a Black Rock neighborhood Thursday.

Officers from the city?s narcotics and vice division responded to a neighbor?s call about some sort of illegal activity going on at a home on Princeton Street. Police say when they arrived, they found drugs inside the three-family house.

At least one person in the home was detained.

Detectives secured the home and are waiting for a judge to sign off on a search warrant. Police say arrests are likely.
