Well that’s one way to make a statement.

A man constructed a potentially deadly bomb at an Iowa sushi restaurant because he didn’t think people took “these types of threats seriously, ” according to a report.

Ivory Washington, 40, assembled an improvised explosive device that looked like a hand grenade at Akebono 515 in Des Moines, KCCI reported.

The restaurant’s owner said that patrons noticed Washington was acting strangely but had “no idea” he was building a bomb.

Washington called the police on himself claiming that his bomb was fake. The bomb squad determined the device was legitimate and authorities immediately took him into custody.

“We tested it to see it if would explode. It did,” Des Moines police Sgt. Paul Parizek told KCCI.

Police said that anyone within a 10-foot radius would have been killed if the device detonated, ABC7 reported.

Washington was charged with possession of an explosive or incendiary material.

He is currently being held in Polk County Jail.
