A Dorchester man was ordered held on $250,000 cash bail today on charges that he tried to rob a business, but was foiled when the owner shot him.

Raymond Sims, 47, pleaded not guilty to the indictment that charged him with armed robbery while masked, authorities said.

Sims walked in to Essential Body Herbs on Blue Hill Avenue on Feb. 15 “with his hat pulled down low over his face and his collar turned up,” said Assistant District Attorney Nicholas Walsh.

He approached two female employees who were behind the counter and demanded money. One of the women pressed the alarm button and ran to tell the store’s owner.

Sims allegedly was armed with a hammer and ran behind the counter and started taking money.

That’s when the owner yelled at Sims and fired his .22 caliber gun at him. Sims ran toward the store’s door and collapsed. He was later treated at Boston Medical Center.

The owner was forthcoming with police, Walsh said, and has not been charged.

Authorities said Sims, who was convicted of armed robbery in 2007, has a 9-page record and 10 aliases.

He is due back in court next month.
