The Boston Police Department reports it is looking for four people for the robbery of $20,000 worth of jewelry at Thai Binh Jewelry, which recently opened at 1283 Dorchester Ave.

According to police, one of the four walked into the shop around 3:30 p.m. on Aug. 11, looked around, declared he didn't want anything they had, then walked out.

In a statement, police say: "As the individual left the store, he appeared to leave the door propped open, allowing the entry of two males and a female. The two males and female then began to smash the cases."

They then fled in a green Camry and a black Volvo SUV, police say.
