Iran on March 13 jailed Hamid Baghaei, a vice president under former hard-liner president Mahmoud Ahmadinejad, following his conviction for corruption, Iranian media reports said.
"Police officers apprehended and transferred the convict to prison," the Tehran prosecutor's office said, cited by the Fars news agency.
Baghaei was sentenced in December to 15 years in prison for embezzlement and illegal business transactions.
Baghai, 48, is very close to Ahmadinejad, serving as his deputy before becoming chief of staff during the former president's second term.
After Ahmadinejad left office, both political factions in Iran; conservatives and reformists began a campaign against him and his close aides. Multiple legal cases were launched against Ahmadinejad and former senior officials of his administration.
The former president reacted to these pressures becoming a vocal critic of the ruling establishment in Iran.
Baghaei was briefly detained in 2015 on corruption charges.
The powerful Guardians Council prevented him from running in the May 2017 presidential election, and he was jailed for a few weeks in July.
