The Oklahoma Highway Patrol Bomb squad took possession of a pipe bomb that was found in a vacant Grand Lake townhouse on Saturday, Aug. 25, said Delaware County Sheriff Harlan Moore.

The pipe bomb was discovered by the homeowners in the garage of one of their rental units located at The Reserve at Grand Lake, a 120-unit community located on the Monkey Island arm of Grand Lake.

People at 12 town homes were evacuated as a precaution.

Moore said the pipe bomb was about nine inches long, was outfitted with a fuse and held a black powdery substance.

Around 9:30 p.m., Saturday, the OHP Bomb squad took the pipe bomb to an undisclosed location and made it safe preserving the evidence, Moore said.

The homeowners of the vacant townhouse said the unit was rented until a couple of weeks ago. Inside the garage they discovered “something highly suspicious” that prompted them to call authorities.

The homeowners declined to give their names.

On Monday, Aug. 27, Moore said he has referred the incident to the ATF for further investigation.
