This weekend's Crime Stoppers centers around a man with active warrants for aggravated child abuse.

25- year old Tyrone McCollum caught the eye of police back in May after a three-year old that had been placed in his care wound up with bruises on her lower neck. The bruises were consistent with being grabbed. 

McCollum's last known address is in the 2400 block of 5th street but he is known to move around the Chattanooga area frequently.

If you have any information on his whereabouts call Crime Stoppers at 698-3333. Your call could earn you a cash reward.
