A former government official once lauded as a Sept. 11 hero was convicted yesterday of taking bribes to let an asbestos-cleanup company overcharge for work at Ground Zero.

A Manhattan jury convicted Mark Jakubek, a former Port Authority field-operations manager, and a former colleague of charges including enterprise corruption.

Jakubek, 50, and ex-colleague Anthony Fontanetta, 61, face mandatory prison terms of at least a year.

The two remain free while their lawyers plan arguments challenging the convictions.

“They’re obviously very disappointed,” said Jakubek’s lawyer, Glenn Abolafia. Fontanetta’s lawyer, Mark Macron, said his client was “despondent.”

Jakubek was hailed for helping rescue people from an elevator during the 2001 terror attacks.
