SOMERVILLE, Mass. (WHDH) -- Police are searching for a suspect whom they believe to be involved in two convenience store robberies in Somerville this month.

A man with a bomber hat on in the middle of summer walked into a neighborhood convenience store in Somerville and demanded money from the cashier. It was about closing time.

The cashier didn't want to talk on camera but said the robber didn't show a gun -- just hollered at him to give him the money.

Frightened, the cashier handed over the money and the suspect ran off down Lowell Street.

It's a surprising crime some neighbors say.

“It’s first heard of it that there’s a robber in the neighborhood, but it is concerning. We live right around the corner. Hopefully they’ll find them and take care of it,” said Megan Baldwin, a neighbor.

Police released the video after a second robbery at a convenience story a half mile away was hit five days later.

Investigators believe it's the same suspect, and now need the community's help to figure out who the robber is.

For those who live in neighborhood, they say they've known the area to be a safe one, and choose not live in fear.

“I don't want to live scared of my possessions or anything like that. You make a choice whether you want to be scared of something or not. By in large I think most people go through their lives unfettered by this kind of thing. It’s traumatic when it happens but it’s not really that bad,” said Milo Macphail, a neighbor.

If you recognize the man in the video contact Somerville police.
