- We went out to Fyrishov and fished up some scrap where we got a mortar grenade with the ignition hat on, says Uppsala magnetic fishing chairman Niklas Larsson to P4 Uppland.
- This one was so small that we could put it in a bucket and then we called the police.
The national bomb protection barred the area and, upon arrival at the site, found that this grenade was also sharp.
After a few hours, they left the site and shipped the grenade to destroy it.
On average, one grenade is found each year in Fyrisån, but what makes this week's two finds so odd is that the lighter hat has remained on.
