State police said they arrested one of three teen-agers wanted in the armed robbery of an Eldersburg veterinary hospital Feb. 28. The youth was arrested yesterday in Queen Anne's County, a spokesman said.
Officers said three teen-agers, one carrying an Uzi-type automatic assault weapon and all appearing about 16 and 17 years old, wore bandanna-type masks when they burst into Carrolltown Veterinary Hospital. They forced one of four employees to a prescription drug cabinet in a rear room and stole 15 bottles of ketamine, a cat tranquilizer, and some cash, police said.
Officers said ketamine is in liquid form, but can be converted to a powder form and snorted or smoked by humans, mostly by teen members of dance clubs where the drug, called Special K, is used.
Investigators said one of the youths entered the office of the hospital in the 1800 block of Liberty Road about 15 minutes before the robbery and inquired about neutering an animal. He asked to use the bathroom.
About 2 p.m., the three burst into the office and demanded cash and drugs, police said. All four employees were forced to lie on the floor as the trio fled on foot.
No one was injured.
The next day, investigators received an anonymous telephone call with information on the robbers.
When officers went to Mount Airy to check on the information, they got a description of the youths and a video from a security camera at a gasoline station.
State police said they believe the youths could be from southeast Frederick County near Mount Airy. The investigation and search for the other teens is continuing.
No charges had been filed against the youth detained in Queen Anne's County as of late yesterday afternoon, police said.
