Arthur Chick, 57, was brought into the Seminole County jail Wednesday afternoon. He didn't know undercover agents were following him all day, waiting for word to arrest him.

The tow truck business owner is charged with one count of possession of child pornography, but more charges are pending. Wednesday, investigators took four computers from the home he co-owns with his father.

Neighbors say they often see him with two young girls who are not his relatives and they say they've seen inappropriate behavior.

"We're looking into certain aspects that may be part of this investigation. I can't go into what we're looking into, but certainly we're going to be interviewing teenagers," says Steve Olson, Seminole County Sheriff's Office spokesperson.

More than a block of Vinewood Drive was closed off because of investigators' concerns for their safety and the safety of the neighbors. They say Chick had lots of guns in his home, a closet full of guns, and more guns and ammunition in his garage. But, investigators say, most, if not all of the weapons, are legal.

"We are looking at the possibility that there might have been a couple that may be [illegal]. One in particular, that is fully automatic, and you need permits for those," says Olson.

Chick has no prior criminal record, so he could have guns. Investigators say chick's house is a mess. They are looking into finding better care for Chick's elderly father.
