Alcohol a Factor in Panettiere Alleged Attack

We have more details on the Panettiere arrest.

Law enforcement tells us Alan allegedly struck wife Lesley at least twice with fist -- a right cross to the left cheek, causing noticeable bruising. We're told both had definitely been drinking.

Alan told cops when they arrived, "I'm Alan. Yeah, I just got into an argument with my drunk wife." We're also told Alan "clearly" was under the influence. Among other things, his eyes were extremely bloodshot and his hair was a mess.

Lesley is the one who called the cops and when they came she asked them to arrest her hubby.
