It's a fishing story like no other. While reeling in his line at Wagon Train Lake on Thursday evening, a fisherman realized his catch wasn't a fish, but a live grenade.

The 31-year-old man was casting off on the lake two miles east of Hickman when his line snagged, Lancaster County Sheriff's Capt. Ben Houchin said.

He reeled it in, saw a grenade attached, and called the Sheriff's Office.

At first, deputies couldn't tell whether the grenade was live, so they called in a member of the Nebraska State Patrol's bomb squad to take a look.

Authorities evacuated the lake and detonated the pineapple-like grenade that looked as if it could have come from the Vietnam era, Houchin said.

"It had some moss and some corrosion on it, but it still had the pin in it," he said. "This is the first time I've heard of a live grenade that's been located by an individual."

It may sound like a fishing story, he said, but deputies believe the man.

"I thought, 'Wow, that's some luck. But they talked to the individual and they think that's exactly what happened."
