An Arizona man caught leaving water bottles in the desert for illegal immigrants has been sentenced to 300 hours of community service and a year of probation, an aid group said.

Walt Staton was convicted in June of littering by leaving jugs of water in a wildlife refuge.

Walt Staton, a member of the group No More Deaths, left full water bottles in December in Buenos Aires National Wildlife Refuge for the illegal immigrants who routinely pass through the 18,000-acre refuge, according to court documents.

A judge sentenced him Tuesday to 300 hours of picking up trash on public property and a year of probation, No More Deaths said in a written statement. He is also banned from the refuge during that time, the group said.
