VALPARAISO, Ind. (AP) -- Porter County police are investigating the recent deaths and mutilation of six cattle and a lamb belonging to a rural Valparaiso farmer.

The Merrillville Post-Tribune and the Times of Munster reported Tuesday that the farmer has told police that three bulls, three steers and a lamb have been mutilated. The mutilations include severed ears and penises.

Police say two of the steers, one in the pasture and another in its barn, and a bull were found dead Nov. 1. The other deaths occurred as early as Oct. 14.

The reports did not identify the farmer.
