Maricopa County sheriff said Joe Arpaio said no charges had been filed or arrests made.

The animal cruelty investigation was continuing and the suspected drugs were being tested, he said.

The search was prompted by reports that pit bulls kept by the rapper, whose real name is Earl Simmons, at the home were not being given enough food or water.

A dozen pit bulls were seized, the bodies of three dogs were dug up in the garden and a variety of assault-style weapons were taken from the home, Arpaio said.
