A police search caused a local school into lock-down mode on Monday.
 
Authorities say they were pursuing Zachary Moore when he fled into a wooded area behind Pleasant Valley Elementary School.  That caused school officials to lock down the campus until the end of classes.
 
Moore, who is wanted for questioning in an assault that occurred last week and has three outstanding warrants, was able to slip away from the police.
 
Anyone with information about Moore is asked to call the Altoona Police Department at 949-2489.
