Updated at 3 p.m. Monday: Revised to include new information from police.

Rowlett police have reopened the stretch of President George Bush Turnpike between Interstate 30 and State Highway 66 after a bomb squad detonated a World War II mortar shell that a man transported into the city.

The man found the old projectile Monday morning in a smaller city nearby and brought it to his home in the 4600 block of Bayonne Drive, said Detective Cruz Hernandez, a spokesman for the Rowlett Police Department.

Hernandez declined to say where the mortar shell was originally found, but he noted that there's no indication that there are other projectiles there.

The Garland Police Department's bomb squad was deployed to the scene. With the help of a robot, squad members took the mortar shell to a field nearby, dug a 3-foot hole and detonated it, Hernandez said.

People who had been evacuated from the area have been allowed back into their homes.

Hernandez said he wasn't familiar with the circumstances surrounding the man's discovery of the mortar shell Monday. But, he added, it wasn't uncommon for World War II veterans to bring home souvenirs from the war, such as grenades or mortar shells.

"Leave it where it is and call law enforcement, wherever it is," Hernandez said. "Don't transport it."
