McLEAN, Va. (AP) - An explosion inside a federal laboratory in Maryland appears to be connected to a security officer's small-scale efforts to manufacture methamphetamine, according to a federal law enforcement official.
Authorities who responded to the explosion Saturday night on the campus of the National Institute of Standards and Technology recovered pseudoephedrine, Epsom salts and other materials associated with the manufacture of meth, said the official, who spoke on condition of anonymity because potential charges are pending.
The materials indicate production of small batches of meth, the official said.
The chemical reaction might have been caused by the manufacturing of drugs, Montgomery County police spokesman Capt. Paul Starks said. Police said that they are investigating the case jointly with the Drug Enforcement Administration and that no charges have yet been filed.
Laura Harris, a spokeswoman for the DEA's Washington, division, confirmed the ongoing investigation Tuesday but declined to comment further.
NIST spokeswoman Gail Porter said the explosion occurred in Building 236 on the institute's campus. That building is not currently used for scientific research, she said, and previously was used for combustible research.
The NIST officer was treated and released from the hospital after suffering injuries in the explosion, and he resigned from his job, Porter said.
The officer suffered significant burns. The officer initially declined treatment and told other officers who responded to the alarm that he had burned himself trying to refill a cigarette lighter.
