A mortar shell was found Thursday afternoon beneath a house in Chattahoochee Hills, police said.

Police there called the Fulton County Sheriff's bomb unit to handle what was believed to be an explosive device, Fulton sheriff's spokeswoman Tracy Flanagan said.

The bomb unit arrived at a home in the 6300 block of Mixon Road, and bomb technicians determined the device was a military mortar round.

After consultation with federal authorities, county bomb technicians determined the shell was safe to remove, and will turn it over to a military explosive ordnance disposal team, Flanagan said.

A bomb-sniffing dog canvased the property where the mortar shell was found without locating any more explosives, authorities said.

It is unclear how the mortar shell came to be underneath the home, or how old the device is.
