“I didn’t even notice him following me until right before it happened. … All of a sudden, he was just there,” the victim said to CBS Boston. “He will do it again unless he’s caught.”

The suspect, last seen on Arthur Street, was believed to be between 18 and 22 years old, according to police.

On Tuesday, authorities were expecting to speak again with both victims again, WHDH added.
