TULSA, Oklahoma - Police are working to track down a teenager wanted for sexually abusing a child he's related to. 

Atom Ward is one of Tulsa's Most Wanted right now.

Police said Ward was last seen at school last Friday, the same day the Tulsa County District Attorney's office filed charges against him. 

18-year-old Ward is wanted on six counts of child sex abuse after a 12-year-old boy confided in a summer camp counselor that ward abused him.

The victim's mom was called and Tulsa police started investigating right away. 

"It takes a lot for a child to disclose something like that, especially when it's against a family member, somebody they know and love, and even trust," said Corporal Mark Kraft. 

Police said the sexual abuse started about six years ago and the victim said it happened nearly every day because Ward was his babysitter.  

Ward's arrest affidavit said he admitted to babysitting the victim on several occasions at the victim's grandmother's house where the two spent time together in the victim's bedroom. 

Corporal Kraft said police aren't aware of any adults knowing the abuse was going on. 

"Somebody trusted him to watch this innocent child," Kraft said. 

The victim said Ward showed him porn and said he wanted to try it.

The child said he told Ward he did not want to but that he made him.

The affidavit said Ward would hold the victim down and muffle his mouth, to silence him. 

It also said Ward admitted to watching porn but denied he let the victim watch it. 

"He's a predator. He has a history of it. He's very recently committed the abuse and he's very likely to do it again if he isn't caught," Kraft said. 

Police said the victim is now safe with his mother. 

If you see Ward, police ask that you do not approach him and call 911 right away.
