NORTH LITTLE ROCK, Ark. (AP) -- A colonel in the Arizona National Guard faces a child sex charge after allegedly using the Internet to arrange a late-night meeting with a young girl in North Little Rock, Arkansas.

A police officer had been posing as a 14-year-old girl.

Colonel Donald Wodash of Chandler is deputy chief of staff for operations for the Army's 153rd Brigade and is involved with border operations.

The 45-year-old Wodash was arrested late last night and charged with computer child pornography

A North Little Rock police spokesman says Wodash was released on his own recognizance.

Authorities say Wodash engaged the investigator in a conversation and, using a Web camera, exposed and touched himself.

Then Wodash arranged a meeting, still thinking he was chatting with a 14-year-old girl. At the meeting site, Wodash was arrested.
