West Virginia ? Four people taken hostage by a gunman at a pharmacy overpowered their captor Monday after he demanded prescription drugs and fired several shots, authorities said.

The 90-minute standoff ended when the hostages, who were barricaded inside the store with the gunman, hit him with something, Sheriff’s Deputy B.E. Ferrell said.

None of the hostages was harmed, but the suspect was taken to a hospital, Ferrell said. The nature of his injuries was not immediately clear, but a witness said he had taken a painkiller and an anti-anxiety drug.

The gunman arrived with a handgun and a sawed-off shotgun, taking six people hostage at the Family Discount Pharmacy in Stollings, about 60 miles southwest of Charleston, according to Logan County 911 Director Marilyn Crosby.

Pharmacy technician Jessica Thompson, 24, said the gunman said he needed drugs but could not afford to buy them.
