A man apparently desperate for drugs pulled a knife on a pharmacist and demanded pills.

North Charleston police are investigating the robbery that occurred at 1:30 p.m. today at the Walgreen’s at Ashley Phosphate and Dorchester roads.

The only description of the man available now is that he was a white male. He pulled a knife on a pharmacist, demanded pills, took them and fled from the store, police spokesman Spencer Pryor said. Investigators were on the scene earlier this afternoon.

Police have not yet said what kind of pills the man demanded or if anyone else got a description of him.
