Lexington firefighters are asking the public to avoid the area of a home where three people were injured as a result of an explosion.

Police say people were injured and transported to the hospital as a result of the incident on Nakomi Drive.

Investigators say there was an estate sale going on at the home at the time, and someone was going through items when an improvised explosive device ignited. One person had a "significant" hand injury, another had a leg injury and the third victim had a head injury. All three are expected to survive.

"The male subject who sustained an injury to his hand as a part of an estate sale had picked up an item that appeared to be a lighter and unintentionally ignited it. It turned out to be an improvised explosive device, and it went off in his hand." Lexington police lieutenant Nathaniel Muller said.

Federal agents are assisting in the investigation, and police say they found additional explosive substances in the home, but there was only one IED.

The person who owned the house died two weeks ago. Police say the man was an "explosive hobbyist," but there is no evidence he created the explosives with an intent to cause harm. Police did not release the name of the estate holder, but our news partners at the Lexington Herald-Leader report the home was last owned by William Schooler, who died unexpectedly at 57.

Police are not expected to file any charges in this case, and investigators believe the explosion as accidental.

ATF agents are assisting in the investigation, and a containment unit was on scene as a precaution if crews found anything which could explode and cause harm. Muller does say possessing homemade explosive devises is against the law.

Authorities are expected to clear the scene by Friday evening.
