VANCOUVER, British Columbia, Feb. 10 (UPI) -- Two tons of ammonium nitrate, which can be used in explosives, disappeared in a clerical error, not through theft, Canadian police said Tuesday.
The Royal Canadian Mounted Police and other agencies began a major investigation Dec. 31 after Kinder Morgan, a large energy company, reported the ammonium nitrate appeared to have vanished while being shipped from Alberta to British Columbia, CTV News reported. The RCMP now reports the chemical was not missing.
"There is no evidence of theft or other criminal involvement in the inventory discrepancy and that a high level of security was in place throughout the process of manufacture, transport and storage of the ammonium nitrate," Sgt. Rob Vermeulen said.
The Mounties said they interviewed 200 people in Canada and Salt Lake City in the course of the investigation.
Ammonium nitrate, used for fertilizer, was an ingredient used in the explosives at the U.S. federal building in Oklahoma City in 1995.
