ROCKLAND, Mass. (WHDH) -- A man, who claimed to be carrying a hand grenade, robbed a Tedeschi Food Shop in Rockland.

Video shows a man with a bandana that covered his face as he held up the clerks with what appeared to be a grenade. The clerks quickly complied with his demands.

The thief was in the store just 30 seconds, got the money and left.

The CEO of Tedeschi Food Shops said he’d love to see the suspect off the streets.

“We would hope they would catch the individual or individuals involved so this doesn’t happen to anyone or anyone else, whether it’s our store or someone else’s in the future. It would be tragic. If we can prevent it and capture him before that happens that would be a good thing for all of us,” said Peter Tedeschi, CEO of food shop chain.

No one has been arrested, but police have recovered the man’s cap -- it is from an Indianapolis motor speedway race from 1995. Police said there may be DNA evidence on the hat, including strands of hair.

Police told 7News they have received numerous leads, but they won’t say if they are close to making an arrest.

Officials believe the man took off on a bike. They are asking anyone with any information to contact Rockland police department at 781-871-3890.
