For the third time in just over a month, Worcester police are investigating a robbery at a CVS pharmacy.
On Wednesday morning, police responded to a CVS on Park Avenue, for a report of an armed robbery. A man in a hooded sweatshirt approached a clerk, and presented a note demanding Percocet pills, police said in a statement.
The note stated that he had a weapon, but one was never shown during the incident, the clerk told police.
The suspect, described as about 5 ft. 7, and weighing about 150 pounds, fled the store, police said.
Anyone with information is asked to call Worcester police at 508-799-8651.
The robbery follows two others at other CVS stores in Worcester since Sep. 4. On that day, the CVS at 400 Grafton St. was robbed. On Sept. 19, the store on Stafford Street was also robbed, police said.
