As mentioned on Park Slope Parents:

A resident of St Johns Place between 7th and 8th Aves) reported a mugging at gunpoint on Saturday night. The resident was apparently walking up St Johns from 7th Avenue. She turned to enter her  house. While looking for her keys, she was approached by two men, who then forced the resident into the house vestibule.

The resident was then threatened with a gun and robbed. These details were posted up and down St. John’s Place this morning.

Does anyone have more details?
