Phoenix police witnessed a man holding his girlfriend's head underwater after he slammed her head on the pool deck.
Police report that on July 11, they responded to an apartment complex near 48th and Van Buren streets for an assault.
Police say as they were gaining access to the pool area, they witnessed 40-year-old Anthony James dunking a woman's head underwater.
Witnesses later told police that the woman "appeared to be unconscious and her body was limp" when James dunked her under the water several times.
After regaining consciousness, the woman tried to escape, but James allegedly grabbed her hair and pushed her head back underwater. He then reportedly slammed her head against the pool deck three times.
The victim was transported to the hospital with brain bleed.
James has been charged with aggravated assault.
