TAMPA, Fla. - Former NBA referee Tim Donaghy arrived at a Tampa halfway house yesterday from a federal prison camp in the Florida Panhandle to serve the rest of his 15-month sentence in a gambling scandal, his spokesman said.

Prison officials put Donaghy on a bus that left Pensacola about midnight to prevent him from having contact with the media, said Pat Zaranek of Executive Prison Consultants. Donaghy is scheduled to be released in October. *
