NEW YORK, Feb 10: The father of a terrorist faced up to 40 years in prison on Friday after his conviction on charges that he destroyed evidence and lied to investigators to cover up his son’s plot to attack the New York City subways in 2009.

Mohammed Wali Zazi, 55, remained free on bail after his conviction in July.

His son, Najibullah Zazi, admitted that he returned from a trip to Pakistan to his family’s Colorado home to practise concocting homemade bombs using chemicals extracted from common beauty supplies. He drove to New York City in September 2009 with plans to attack the subway system in a ‘martyrdom operation’ before he learned he was being watched by the FBI and fled back to Colorado. The plot was sanctioned by Al Qaeda.

The elder Zazi, an Afghan-born US citizen, was found guilty of conspiracy and obstruction of justice.

When it became clear Najibullah Zazi was a suspect and family members were getting grand jury subpoenas, a cousin said “Uncle Wali” recruited him to get rid of plastic containers of peroxide and other evidence. The family agreed to codename the chemicals “medicine” in case the FBI was eavesdropping, he said.

He also claimed his uncle told them not to say anything if they were asked questions.

Mohammed Zazi has maintained his innocence.

“There are so many things that didn’t come out in court,” the former taxi driver said after his conviction. He didn’t elaborate.

Najibullah Zazi, who pleaded guilty to federal terrorism charges and is awaiting sentencing, faces life in prison.

One of Zazi’s former high school classmates also has admitted in a guilty plea that they wanted to avenge US aggression in the Arab world by becoming martyrs.—AP
