VANCOUVER, Wash. -- Police say a 49-year-old Vancouver, Wash., man has been charged with receipt of child pornography.

Alan Becker was charged Tuesday in U.S. District Court in Tacoma.

According to the criminal complaint, a Vancouver police officer was called to an apartment complex, where he met a woman who said she had been assaulted by her boyfriend, Becker.

The woman explained that the fight with Becker included him grabbing her by the hair and ripping the phone from her hand and breaking it to prevent her from calling 9-1-1.

The woman alleged that Becker had child pornography on his computer and on various disks.

Police say a review of the computer and materials taken from Becker's home revealed 448 images of child pornography and 475 movie files of child pornography.
