Authorities are searching a canal in connection with an older case.
Video from Air15 showed at least one police diver searching the canal near 12th Street and Indian School Road Tuesday afternoon.
A Phoenix Police Department spokesman said officers are looking for evidence in connection with a previous investigation, and they are not looking for a body.
An ABC15 reporter on the scene observed police conducting what appeared to be a grid search, with one person in the water occasionally placing items from the bottom of the canal up on the bank. Police were slowing working their way west.
No further information was immediately available.
