Police continue to search for a man who robbed a gas station while holding a knife in Easton, Massachusetts on Tuesday evening.
The robbery happened at the Mutual Oil on Washington Street just before 6 p.m.
The clerk told police that the masked man jumped over the counter and demanded cash while holding a foot-long knife.
The robber allegedly told the clerk to crawl outside and wait until he got away. The masked man then fled the scene with more than $700.
The FBI told NBC Boston that they are investigating whether the incident is related to other robberies that have occurred in the area recently.
