A French photographer held nine months in an Afghan prison was freed Saturday and said police had debated whether to formally arrest him or kill him and blame guerrillas who brought him into the country.

"I wasn't treated too badly, but I was morally brutalized," said Alain Guillo. "For the first four months, I had no newspapers, books or paper. I was always under surveillance and deprived of fundamental rights."Guillo, 45, who spoke to reporters after arriving in New Delhi, left the Indian capital for Paris early Sunday. He was freed in Kabul after Gilbert Perol, secretary-general of the French Foreign Ministry, presented a letter from President Francois Mitterrand to Afghan leader Najib.

At the news conference in the home of Andre Lewin, the French ambassador, Guillo said he had no advance word of his release.

He said Afghan security police captured him Aug. 28 after he sneaked into Afghanistan with Moslem insurgents. His arrest was not announced until mid-September.

"For 15 days, they hesitated between killing me on the spot and arresting me formally," he said. "They would have blamed the killing on the mujahedeen," or Afghan insurgents.
