Calgary's police chief questions whether a reward would help the investigation into the disappearance of a five-year-old boy and his grandparents.

Nathan O'Brien was reported missing Monday when his mother went to pick him up after a sleepover at the grandparents — Alvin and Kathy Liknes.

No one was home and an Amber Alert was issued by police.

Nathan's father, Rod, says the family would be offering a reward.

Chief Rick Hansen says in cases like this a reward can just cause more work for police because all kinds of people could step forward with bogus tips that must be checked out.

Hansen told a radio show (Morning News CHQR) that if people have information about a case they will usually call the Crime Stoppers phone tip line.
