DES MOINES, Iowa (AP) — Des Moines police are looking for a man they say knocked out his father’s girlfriend with a package of frozen bratwurst. Police tell the Des Moines Register that officers were called to a hospital, where the 50-year-old woman was receiving staples to close a gash on the back of her head.

The woman told police that she kicked her boyfriend’s 44-year-old son out of their home around 2 p.m. Thursday. As he was preparing to leave, she said, she tossed a package of frozen brats belonging to the son into the yard. She says when she turned to walk back inside, the man hurled the sausages at the back of her head, knocking her unconscious.

An arrest warrant charging the man with assault has been issued.
